How do I transpose a vector within a cell?

I have a 1x5 cell each containing 4000 points of data. The 4000 points of data fill the columns, Id like to have each 1x4000 turn into a 4000x1. How to do this? Easy question right?

Thanks in advance!

cellfun(@tranpose, yourcellarray, 'UniformOutput', false)

However, there's little point in using a cell array if all your vectors are the same size, so you would be better off transforming that into a 2-d matrix, so:

[yourcellarray{:}]      %for a 4000x5 matrix

[yourcellarray{:}].'    %for a 5x4000 matrix

Error using cellfun Input #3 expected to be a cell array, was char instead.

I got this error. What could that be?

When I do just the [yourcellarray{:}] it turns it into a 1x16000 cell. I feel like we are close.

Actually, it worked. I do not know what I did the first time. Thank you!

You must have misspelled 'UniformOutput'

it turns it into a 1x16000

My mistake. The code I wrote is for column vectors, not row vectors. With row vectors:

vertcat(yourcellarray{:})   %for a 5x4000 matrix

vertcat(yourcellarray{:}).' %for a 4000x5 matrix

A{1} = rand(5,1) ; 
A{2} = rand(5,1) ; 
A{3} = rand(5,1) ; 
A{4} = rand(5,1) ; 

B = cellfun(@(x) x',A,'un',0)
