Hello community,
I want to use the MATFILE command to access specific data in .mat-files. Is there a function which returns true if the .mat-file format is 'v7.3' and false otherwise?
I know you can check this in the command window using
type myfile.mat
However you cannot use TYPE within a function, which is what I want to do.
Thanks in advance
David

You can use evalc to capture the output of type
function tf = getmatv(fname)
x = evalc(['type(''', fname, ''')']);
tf = strcmp(x(2:20), 'MATLAB 7.3 MAT-file');
end

I was really answering the "you cannot use TYPE within a function" part of the question. I am not sure you want to use TYPE, but I wanted to provide a way to do it.

You can also use fileread() to pull in the entire file, and then examine the first few characters of it.

type(FileName)
should work fine, where FileName is a string containing the file name, e.g.
FileName='myfile.mat'
