i have a coloum data, how to normalize it in Source Scanning Algorithm

how to set the column data to a range of 0-1; what is the first step,get absolute value or normalize?

Answer 1

[Mischa Kim]

The simple approach:

abs(data)/norm(data)

Are you concerned about algorithm speed?

[Roger]

yes ,but not now

Answer 2

[Wayne King]

If you want the largest element in the vector to be mapped to 1, use the linfinity norm.

x = randn(100,1);
y = abs(x)/norm(x,Inf);
