I have code that pulls files successfully except once the first loop is completed fnm is overwritten and the previous files contents disappear. I need to add code that allows each loop to store the file contents(a Matrix). Once the files are saved and the for loop is complete dependent of the size(CatRow)I will concatenate the matrixes together.
%
for ii= 1: CatRow
[num,txt,data] = xlsread(stateTable{ii,1})
fnm = sprintf('file_%d.mat',ii);
save(fnm,'data');
horzcat(fnm's into one matrix)
end

all_data = cell(CatRow,1);
for ii= 1: CatRow
[num,txt,data] = xlsread(stateTable{ii,1})
fnm = sprintf('file_%d.mat',ii);
save(fnm,'data');
all_data{ii} = data;
end
big_data = horzcat(all_data{:});
I have to ask whether you really want to horzcat() them together. If they are the same size, more common would be to
big_data = cat(3, all_data{:});
which would concatenate them on the third dimension.

I had some typing mistakes in what I posted; I have corrected them.
To get a 2 x 1 cell you must have used vertcat() or cat(1) instead of horzcat()
