Hiring guide for MATLAB Component Runtime (MCR) 8.0 and later versi Engineers

MATLAB Component Runtime (MCR) 8.0 and later versi Developer Hiring Guide

MATLAB is a numerical computing environment and programming language developed by MathWorks. First released in 1984, MATLAB was originally developed for the computing needs of engineers and scientists. It has since become a popular tool for a wide range of applications, including data analysis, machine learning, and image processing. MATLAB is available for both Windows and macOS, and can be used on a variety of hardware platforms. The MATLAB Component Runtime (MCR) is a software library that provides the necessary components for MATLAB to run on a system. MCR is included with MATLAB, and is also available for download from the MathWorks website. MATLAB is a powerful tool that can be used to solve a wide range of problems. However, it is important to note that MATLAB is not a general-purpose programming language. It is designed specifically for numerical computing, and does not have the same features as languages such as Java or Python.

First 20 minutes

General MATLAB Component Runtime (MCR) 8.0 and later versi app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in MATLAB Component Runtime (MCR) 8.0 and later versi application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

Can you explain how you would install MATLAB Component Runtime (MCR) on a system?
First, you need to download the MCR installer from the MathWorks website. After downloading, run the installer and follow the instructions. Make sure to choose a location that is accessible to the system's PATH environment variable. Once the installation is complete, you can verify it by running a deployed MATLAB application.
What are the system requirements for installing MCR 8.0 and later versions?
The system requirements include a compatible operating system like Windows, Linux or Mac, enough disk space for installation, and a compatible version of MATLAB compiler. The specific requirements can vary depending on the version of MCR.
Describe the difference between MATLAB Compiler and MATLAB Component Runtime?
MATLAB Compiler is a tool that allows you to share MATLAB programs as standalone applications, while MATLAB Component Runtime (MCR) is a runtime environment that allows you to run these standalone applications on systems without MATLAB installed.
How would you ensure that an application uses a specific version of MCR?
You can specify the version of MCR that an application should use during the compilation process. This is done by using the -R option followed by the MCR version in the mcc command.
What are the steps to compile a MATLAB application using MCR?
First, you need to write and test your MATLAB application. Then, you use the MATLAB Compiler (mcc) to compile the application, specifying the target as a standalone application. The mcc command also includes the -R option to specify the MCR version. Finally, you distribute the compiled application along with the MCR installer.

Next 20 minutes

Specific MATLAB Component Runtime (MCR) 8.0 and later versi development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

Describe the difference between MCR and MATLAB Compiler SDK?
MCR is a runtime environment for running standalone applications created with MATLAB Compiler, while MATLAB Compiler SDK is a tool that allows you to create components that can be integrated with applications written in other languages.
How would you troubleshoot a problem where a deployed application fails to run due to MCR?
First, I would check if the correct version of MCR is installed and that the PATH environment variable is set correctly. If that doesn't solve the problem, I would look at the error messages, which may indicate issues like missing dependencies or incompatibilities between the application and the MCR version.
What are the steps to update MCR to a newer version?
To update MCR to a newer version, you need to first download the new version from the MathWorks website. Then, you uninstall the old version and install the new one. Finally, you need to recompile your MATLAB applications using the new MCR version.
How would you create a standalone application that can be run on a system without MATLAB?
You can use the MATLAB Compiler to create a standalone application. This process involves writing and testing your MATLAB code, then using the mcc command to compile the code into an executable or binary file. The compiled application can be run on any system with the appropriate version of MCR installed.
What are the limitations of using MCR for running MATLAB applications?
One limitation is that MCR does not support all MATLAB features, such as certain graphics or interactive features. Also, the performance of applications run with MCR can be slower than running them in MATLAB. Finally, each version of MCR is tied to a specific version of MATLAB, so you need to manage multiple versions if you have applications compiled with different MATLAB versions.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with MATLAB Component Runtime (MCR) 8.0 and later versi.

What does the following MATLAB code do? 'a = [1 2 3 4 5];'
a = [1 2 3 4 5];
This code creates a 1-dimensional array 'a' with elements 1, 2, 3, 4, and 5.
What is the output of the following MATLAB code? 'A = [1 2 3; 4 5 6]; B = A';'
A = [1 2 3; 4 5 6];
B = A';
This code creates a 2x3 matrix 'A', then transposes 'A' and assigns it to 'B'. The output will be a 3x2 matrix 'B'.
What does the following MATLAB code do? 'A = [1 2 3; 4 5 6]; B = A(1, :);'
A = [1 2 3; 4 5 6];
B = A(1, :);
This code creates a 2x3 matrix 'A', then assigns the first row of 'A' to 'B'. So, 'B' will be a 1-dimensional array with elements 1, 2, 3.
What will be the output of the following MATLAB code? 'parfor i=1:5, disp(i), end'
parfor i=1:5, disp(i), end
This code uses parallel for loop to display numbers from 1 to 5. However, the order of the numbers might not be sequential because the iterations of the loop are executed in parallel.

Wrap-up questions

Final candidate for MATLAB Component Runtime (MCR) 8.0 and later versi Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle MATLAB Component Runtime (MCR) 8.0 and later versi application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between MCR and MATLAB Runtime?
MCR and MATLAB Runtime are essentially the same thing. MATLAB Runtime is just the new name for MCR starting from version R2012b. Both are used to run compiled MATLAB applications on systems without MATLAB installed.
How would you manage multiple versions of MCR on the same system?
You can install multiple versions of MCR on the same system by installing each version in a separate directory. You can then specify the version to use by setting the PATH environment variable to the directory of the desired MCR version before running a MATLAB application.
What are the steps to deploy a MATLAB application on a web server using MCR?
First, you need to compile your MATLAB application into a standalone application using MATLAB Compiler. Then, you install the appropriate version of MCR on the web server. Finally, you deploy your standalone application on the web server, making sure that the server's PATH environment variable includes the location of the MCR installation.
