Solution to a vector to matrix recoding problem
View vm-rp
A is 100 dimensional vector containing integers N between [1 and 10] (inclusive) distributed at intervals of 10:
at index x -> N
at index 1 -> 1
at index 11 -> 2
at index 21 -> 3
Need to recode A into a 10x100 (Rows x Columns) matrix such that each column is a 10 dimensional vector y with y(x) = 1 the rest is 0
