MATLAB: Extract an array of doubles from a nested cell array

Question

Hello,

I have a cell array X which is {n x 9}. All the cells in column 9 contain a cell array and an array of doubles in this form:

{{1×421};[1×421]}

I would like to extract all the doubles to a new matrix(n x 421). Is there a way to do this with out using for loops?

Many thanks

Struan

Answer 1

out = cell2mat(cellfun(@(x)x{2},X(:,9),'un',0))
