How to extract the data from cell to normal matrix

Hi everybody,

I am looking for an answer to my problem. I have 1x600 cell data which every cell contain 1888x4 matrix. The first column is x, the second is y, the 3rd is u and the 4th is z. I would like to collect all of x column into 1 matrix. In the end, I will have x_collection = 1888x600 matrix.

Does anyone know how to do it? I am a newbie here. Really appreciate your help

Answer 2

cat(3, yourcellarray{:})

will result in a 1888x4x600 matrix, if you prefer the 4 columns to be pages (i.e. a 1888x600x4 matrix):

permute(cat(3, yourcellarray{:}), [1 3 2])
