How can i group each column of a matrix after i split a matrix into columns.

for eg, i have a matrix "mat = 10*rand(x,y)"

after i split the matrix by columns into y number of groups,how can i group them in such a way that grp1=column1 of matrix mat, grp2=column2 of matrix mat and so on..... all the way until group y = column y of the matrix?

I would avoid creating the groups like you're proposing ( FAQ) and instead continue to operate on the matrix as it is.

What is your end goal? Given:

mat = 10*rand(6,7)

What do you want to do with mat?

i would like to obtain the maximum value of each column in this a random matrix w/o the use of inbuilt function max.

What do you have against max()???

[Sean de Wolski]

How about

-min(-mat)

or

nanmax(mat)

?

mat=rand(x,y)
for k=1:size(mat,2)
c=mat(:,k) % your column k
% Do what you want
end
