MATLAB: Are there C++ libraries available to access MATLAB generated MAT-files from the C++ application

cclassclasseslibrarymatMATLABobjectsplusplusplus

I am currently using the C MAT-file API to read and write MAT-files in my C++ application. I would like to know if there is a C++ equivalent to this.

Best Answer

MATLAB does not provide a C++ equivalent of the C MAT-file API libraries. You should be able to seamlessly use the the C MAT-file API from a C++ program with suitable programming.

Yes, you can write standalone applications using the MAT-file library than can run independent of MATLAB. You just need to copy over the required DLLs. See Deploying MAT-File Applications.

MATLAB: Convert mat-files into CSV.files

d=dir(fullpath(dirname,'*.mat'));
for i=1:length(d)
  load(d(i).name     % will leave whatever variable is in mat-file in memory
  [p,n]=fileparts(d(i).name);         % get path, name w/o extension
  csvwrite([fullfile(p,n) '.csv'],X)  % write to name w/ .csv extension
end

The above use X as a placeholder for the variable containing the data LOADed; use whatever is that name. Of course, also assumes all the files are symmetric with the same name; if not use the functional form of load and the appropriate structure name retrieved.

And, of course, this begs the question of why one would do this... .mat files are much more accurate in keeping full precision whereas .csv files are a limited number of decimal places; are much faster to read/write and take up far less disk space besides (albeit that's pretty much a "don't care" item any more).
