How can I get a m file from a cpp file?

i have also met this problem. MinGW64 Compiler (C++) with error: lack of header C++ file 'fftw.h'. if you have solved it, please tell me. thanks

Answer 2

[Hugo Ochoa]

Thanks Walter but

y = perform_curvelet_transform(x,options)

I can't run it because of the options. Should I put in options, the sam options instead m,n the matrix x?

 C = fdct_wrapping_mex(m,n,nbscales,nbangles,finest,randn(m,n));

I couldn't use it but i Believe you are right

Thanks again

[Walter Roberson]

options.n = n;

looks like it might be the only mandatory option.

[Hugo Ochoa]

other problem

y = fdct_wrapping(x, is_real, finest, nbscales, nbangles_coarse);

is function that I have in your suggested file(line 21), but this function invokes

C = fdct_wrapping_mex(m,n,nbscales,nbangles,finest,randn(m,n));

Again, so is a kind of loop with no end

The problem is I get the Sparco matlab freesoftware I tried to run exSeismic.m so I get curveLab, finally I could not run that file because I could not compile the c files in curvelab

[Walter Roberson]

No, the file https://www.mathworks.com/matlabcentral/fileexchange/5104-toolbox-wavelets/content/toolbox_wavelets/perform_curvelet_transform.m includes the source for fdct_wrapping and its inverse right there, without invoking any mex function for it.

I could not compile the c files in curvelab

You should have asked directly about that.

Which MATLAB version do you have? Which operating system do you have? Which compiler(s) do you have installed? What result do you see for

mex -v -setup

?
