Hi all,

Just want to preface saying I'm a newbie with Matlab so thank you for your help and patience.

I've got a 10x1 cell titled "Period," where each row contains a double ranging from 771x224 to 771x240 (see screenshot below). I want to find the inverse of each Period value (1/Period value) in each double, for the entire Period cell, and place into a new 10x1 cell titled "Frequency". To my understanding, I cannot use cellfun to perform this.

Thank you in advance, I appreciate any help / tips!

Why do you think you cannot use cellfun?

Period = {[2 3; 5 7],[11 13]};
Frequency = cellfun(@(x)1./x,Period,'UniformOutput',false);

Thank you for your help. I was getting lost in the documentation for cellfun and didn't realize I could define my own function. This is helpful and I appreciate your quick response! I aim to decode documentation more thoroughly as I continue my Matlab practice.

Have a nice day and stay well!
