This can be achieved by scaling the data returned from the PREMNMX function. For example, if you want the data in the vector "X" to be scaled between 0 and 1, rather than -1 and 1, use the following code:
x = premnmx(X);
y = (x+1)/2
In general, if you want the data in "X" to be scaled between "a" and "b", use the generalized code:
x = premnmx(X);
y = (x+1)*(b-a)/2+a
