hello I am c# programmer. after coding using matlab, I was faced with a problem. I can't convert below c# codes to matlab:
public double[][] Transpose(double[][] M)
double[][] R = new double[M[0].Length][];
for (int c = 0; c < M[0].Length; c++)
R[c] = new double[M.Length];
for (int i = 0; i < M.Length; i++)
for (int j = 0; j < M[0].Length; j++)
R[j][i] = M[i][j];
return R;
Please Help me to convert this code to matlab code and not recommend to use matlab function. Thanks

I find solution for creating dynamic array in matlab:
How to Create it:
x = {zeros(1,30);zeros(1,20);zeros(1,10)};
x{4} = x;
How to Access it:
x{4}{1}(25) = 5;
Good luck

... and that’s the one thing ‘ar fa’ needs to know.
Now, a universal polymath!

R = M'
Or if you want to strictly transpose for complex arguments as well,
R = M.'

The second, non-conjugate transpose is the correct answer.

For your specific problem, some useful pages are Matrix Indexing in MATLAB, Loop Control Statements and Create Functions in Files. But you seem to be starting from zero knowledge of MATLAB, so you really should start with a tutorial. It wouldn't do you much good if we simply converted your function to MATLAB because you wouldn't know what to do with it.
