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?

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
