Use the functional form for writing your report and build up the filename, something like this:

for n = 1:numFiles
  fn = ['report', int2str(n), '.xls');
  % now use this filename, e.g.,
  xlswrite(fn, ...)
end

Got any guesses since it’s wavwrite to write them out? Try using lookfor at the MATLAB prompt or searching the doc. What happens if you look up wavwrite? Does it help you at all?

Michael: Thanks. That’s perfect. To get to the end result needed: [nameWithSpace{:}] strings everything out into a char array.

You can have the concatenation even easier, without resorting to arrayfun and anonymous functions:

files = dir(’*.mat’);
namesWithSpace = strcat(newpath,{files.name},{’ ‘});

I think this maybe what you want

% arr - the n-dimensional input matrix
% dim - the dimension to iterate over
% fh - the function handle to process the iteration
function iterate_dim(arr, dim, fh)
…n = ndims(arr);
…m = size(arr, dim);
…idx = repmat({’:'}, n);
…for i = 1:m
……idx{dim}=i;
……r = arr(idx{:});
……fh(r);
…end
end

to use

a = rand(10);
iterate_dim(a, 1, @(row) disp(row))
iterate_dim(a, 2, @(col) disp(col))

I have not checked the code above so I don’t know if it works as advertised :). Also I think the inner indexing
will be slow as matlab will not be able to JIT the indexing. Is there a smarter way to do the indexing?

wav-files use a losy compression scheme so when you read the data back in, it doesn’t match the mat-file data exactly.

But I think you are pointing my mistake in the M-code! The for loop should read

%% Loops over the Files
%
for ind = 2:length(matfiles)
    data = load(matfiles(ind).name);
    wavwrite(data.y,data.Fs,matfiles(ind).name(1:end-4));
end

I have fixed up that and another small bug in the code in the blog itself.
