normalize_cols is a function that scales each column of a matrix so that it has norm 1. That is, each column of the matrix is divided by its norm.

Syntax

  • Y = normalize_cols(X)

Argument descriptions

  • X: A matrix to have its columns normalized.

Examples

>> X = [1 0 1;0 2 1i;0 0 -1;0 0 -1i]

X =

   1.0000                  0             1.0000          
        0             2.0000                  0 + 1.0000i
        0                  0            -1.0000          
        0                  0                  0 - 1.0000i

>> normalize_cols(X)

ans =

   1.0000                  0             0.5000          
        0             1.0000                  0 + 0.5000i
        0                  0            -0.5000          
        0                  0                  0 - 0.5000i
