I am looking to create an array of file names on every row of a matrix,and I keep getting
"In an assignment A(:) = B, the number of elements in A and B must be the same." or "Assignment has more non-singleton rhs dimensions than non-singleton subscripts"
This is what I have right now:
hello = 0;
for i = 1:8
str = strcat('world',' ', num2str(i))
hello(i,:) = str;
end
hello

Richard - you initialize hello as a scalar instead of as a matrix or cell array so this is going to lead to problems. Try doing the following instead
myFilenames = cell(8,1);
for i = 1:8
str = strcat('world',' ', num2str(i));
myFilenames{i} = str;
end
where
myFilenames =
'world1'
'world2'
'world3'
'world4'
'world5'
'world6'
'world7'
'world8'

Yes. No need as far as I can tell to store all the filenames. Use this:
thisFilename = sprintf('%s%d_Processed.csv', v, k);
[fieldname(k), csv] = container(folderX, thisFilename);
assuming v is a string.
And I can't see that container() is correct - I think a huge portion of it is missing and what's there is almost useless. What you have there would cause an error but not the one you mentioned. It gets data, but doesn't do anything with it, and it returns fileID and csv which it never created. Because so much code is missing, and you did not include the whole error message, just a small part of it, we can't really debug it anymore.

%hello = 0;
for i = 1:8
str = [strcat('world',' ', num2str(i))]
hello{i,:} = str;
end
