How do I combine vectors to form a matrix?

I am trying to run a loop which puts column 5 from every cell in this array shown below into a new matrix:

This is my code at the moment:

combined = [6050,54]

for i=1:length(mydata)

combined(:,i) = mydata{i,1}(:,5);

end

This is the error I recieve:

Subscripted assignment dimension mismatch.

Error in MatlabCoursework (line 84) combined(:,i) = mydata{i,1}(:,5);

combined = cell2mat(cellfun(@(x)x(:,5),mydata,'un',0));
