MATLAB Code Generation is a powerful feature that allows you to convert MATLAB code into C or C++ code. This process, also known as MATLAB Coder, enables developers to create standalone applications or integrate MATLAB algorithms into larger systems.
Code generation serves several important purposes:
To generate code from a MATLAB function, follow these steps:
codegen
command to generate C/C++ code-args
optionLet's create a simple MATLAB function and generate C code from it:
% myFunction.m
function y = myFunction(x)
y = x^2 + 2*x + 1;
end
% Generate C code
codegen myFunction -args {0}
This command generates C code for myFunction
, assuming a scalar input.
MATLAB Code Generation can handle more complex operations, including matrix manipulations:
% matrixOps.m
function result = matrixOps(A, B)
result = A * B' + eye(size(A, 1));
end
% Generate C++ code
codegen matrixOps -args {ones(3,3), ones(3,3)}
This example generates C++ code for matrix multiplication, transposition, and addition operations.
MATLAB Code Generation integrates well with other MATLAB features:
MATLAB Code Generation is a versatile tool that bridges the gap between rapid prototyping in MATLAB and efficient deployment in C/C++. By leveraging this feature, developers can significantly enhance the performance and portability of their MATLAB algorithms.
