I have a cell array y={1X5} each cell contains 256*256*10(3rd dimension will vary for each cell) 3D vectors. My need is to convert the cell array to matrix of the form 256*256*100. Could anyone please help me to write the fastest simple code. Thanks

You mean the result is 256x256x50

if all the 3rd dimension has the 10 exactly the result will be 256*256*50 otherwise it varies

在 MATLAB Online 中打开

A=cell(1,5)
A=cellfun(@(x) randi(10,256,256,10),A,'un',0) % ---Example----
B=cat(3,A{:});

Could you please explain this code? Thank you so much

The first two lines of it create random data of the proper size, for the sake of illustrating the third line which is the line you need to use on your own cell array.
