Thank you for your response. I have matrix data (numerical fields), your answer gave me just numbers from 1 to 10. How can I read matrices data?

Hello Azzi, Thank you for your cooperation.. here exactly what I have. I have file (data.mat) consists of file named(FS (1X10 struct with one field)) . these ten file as matrices (4000X234). I would like to read them and apply an equation (any equation as example). That will help me a lot in my research.
Thank you
Riyadh

suppose you have this matrix
A=[1 2;3 4;5 6]
What operation you want to apply?

Example:
arrayfun(@(IDX) mean(YourStructArray(IDX).TheField(:)), 1:numel(YourStructArray))
