How to replace every element of a matrix with another column matrix?

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
