strange - range
The range is the distance between the largest and smaller value, [r]=strange(x) computes the range of vector or matrix x.
[r]=strange(x,'r') (or equivalently [r]=strange(x,1)) give a row vector with the range of each column.
[r]=strange(x,'c') (or equivalently [r]=strange(x,2)) give a column vector with the range of each row.
