Hi everyone,

I have the following cell array

Max_Col_Cell(9,10,15)

I want to isolate every combination of the first two elements (9,10) for all the 15 values of the third element and create new vectors having one column with 15 rows.

For example create a vector having (1,1,:). Another vector having (2,1,:) etc....

I am trying to write a for loop but its not working.

How can i do this?

Ilias

Why do you want to create seperate vectors each set of 15 elements. See here why it is a bad ideahttps://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer. Using a matrix is much better solution.

Thank for your reply.

I thought that having seperate vactors it would be easier to handle them cause i want to extract the maximum value of those 15 elements.

Is it possible to rearrange in the way that i want in a matrix?

Does your cell array have only numeric values in it?

If yes, then

maxVal = max(cell2num(C),[],3)

where C is your cell array.

I guess the cyclist wanted to write

maxVal = max(cell2mat(C),[],3)

Sorry, yes, cell2mat. (I also have cell2num from the File Exchange.)
