[filename filepath]=uigetfile('*.xlsx','multiselect','on')
length(filename)
How to find out how many columns or length (what is better?) are in the matrix [filename]?
If I select 2 files (test0.xlsx and test1.xlsx) my ans = 2
If I select 1 file (test1.xlsx) my ans is 10, sth its wrong ;/
*I just want to do a script that will detect, maybe someone have good idea for that :)
if I have 1 selected file
something1
else I have 2 selected files
something2
end
Thanks for help

if ischar(filename) % you select 1 file
something1
else % your filename is cell of char/string % I have 2 selected files
something2
end

hawk5577 - use size to determine the dimensions in your matrix. Since you are interested in the number of columns, then
numFiles = size(filename, 2);
