MATLAB: How to combine vectors to form a matrix

cell arrayerrorloop

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);

Best Answer

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