HI all again,

I have one vector A and a matrix B:

Vector A has integers values from 0 to 6, A=[0 1 3 2 0 4 5 2 1 6]' (column vector, 10 values)

Matrix B has size 10 X 6, where in each row the element of A is split into ones, until the A(i) value is reached

for example B would be like that B=[0 0 0 0 0 0;1 0 0 0 0 0;1 1 1 0 0 0;….]

Is there any quick way to do it, avoiding multiple "if'?

thanks a lot,

Nikolas
