MATLAB Compiler¶

MATLAB Compiler™ lets you share MATLAB® programs as standalone applications.

All applications created with MATLAB Compiler use the MATLAB Runtime, which enables royalty-free deployment to users who do not need MATLAB. You can package the runtime with the application, or have your users download it during installation.

The MATLAB website has more about MATLAB Compiler support for MATLAB and toolboxes, and a helpful video about creating standalone applications.

Example¶

How to build MATLAB standalone applications from scripts.

On Perlmutter with ThinLinc:

module load matlab matlab-mcr

Copy the example below to a file in your home directory and launch MATLAB:

matlab

This example shows a matrix factorization, using a function that performs a Cholesky decomposition. It will read data from and write results to CSV files. This script produces an upper triangular matrix R from the diagonal and upper triangle of matrix A, satisfying the equation R'*R=A. A_path is the path to CSV-formatted data for A and outpath is where R will be written to as a CSV file.

% decomposition.m
function R = decomposition(A_path, outpath)
% A_path: Path to CSV data
% A: Matrix, positive definite
% R: upper triangular matrix R from the diagonal and upper 
% triangle of matrix A, satisfying the equation R'*R=A
 A = csvread(A_path);
 R = chol(A);
 csvwrite(outpath, R)

From the command line, you can also use the MATLAB compiler as follows:

mkdir build; cd build

mcc -m ../decomposition.m

After the build process is completed, execute the program with the following syntax and the needed input arguments. For this particular example, the variables are A: Matrix, positive definite and outpath: path to where results will be written:

Under

$HOME/matlab_examples/build/decomposition/for_testing if GUI was used

or

under $HOME/matlab_examples/build if mcc was used:

./run_decomposition.sh $MCR_ROOT $HOME/matlab_examples/data.csv ./out.csv

The complete documentation for mcc can be found in the MATLAB documentation.
