Hello,
I have a matrix y=[0,1,4,2,5,1,5,9,8,.........] it contains n numbers from 0 through 9.
I want to replace each element with a column matrix.
for ex- all 0s in y should be replaced with [1;0;0;0;0;0;0;0;0;0]
like wise all 1s should be replaced with [0;1;0;0;0;0;0;0;0;0]
.
going on 9 should be replaced with [0;0;0;0;0;0;0;0;0;1]
Is there any efficient way to do this?

If you don't have the Deep Learning Toolbox, try this:
y=[0,1,4,2,5,1,5,9,8]
output = zeros(9, length(y))
for col = 1 : length(y)
row = y(col) + 1;
output(row, col) = 1;
end
