Hi,
I have a A=78757x1 cell, consiting of {125×15 double} matrices.
How can I calculate the mean of all (78757) matrixes, ( "element-by-element" for each matrix) so that I have a mean Matrix of 125*15 at the end. A contains also sometimes NaN entries.
Thanks,
Chris

M = mean(cat(3,A{:}),3,'omitnan')

Try
mean(cat(3,A{:}),3,'omitnan')
The omitnan flag will ignor the nan entries in the computation of the mean.
