MATLAB Coder™ generates standalone C and C++ code from MATLAB® code. The generated source code is portable and readable.MATLAB Coder supports a subset of core MATLAB language features, including program control constructs, functions, and matrix operations. It can generate MEX functions that let you accelerate computationally intensive portions of MATLAB code and verify the behavior of the generated code.

assert one dimensional double array of unlimited length (matlab coder)
I am currently using this code:
assert(isa(values,'double'));
assert(size(values, 1) <= 1000);
to persuade matlab coder to make values a one dimensional array. The end aim is to be able to interface with it via C# and PInvoke. This creates a C…

Datatype conversion?
Given a Differential Equation in matrix form:
f = @(t,y) [(a*y(1) + b*y(2)); (c*y(1) + d*y(2))];
a=-2; b=-1; c=1; d=-4
Solutions to my differential equation problem are
x(t)= e^(-3t) (t+1)
y{t)= e^(-3t) *t
General Solution is
Y(t)= e^(-3t)…
