why reading .xls file using xlsread returns empty variables?

10 views (last 30 days)
Hello
I have some data in a .xls file. the file content is four colunms. the first row is a header then all others are numbers.
I tried to simply use
[ndata, text, alldata] = xlsread(filename)
but it does not return anything
ndata =
[]
text =
0×0 empty cell array
alldata =
1×1 cell array
{[NaN]}
How can I solve this problem?
Thanks!

Thank you!
your comment made me realize the problem.
The problem is the data is not in the first sheet of the .xls file.

The problem is the data is not in the first sheet of the .xls file.
I needed to sort the xls sheets before using
[ndata, text, alldata] = xlsread(filename)

it's because I'm older and I'm always using "old" functions , but I'm improving lately on new stuff
