norm

norm (replaces TNorm)

The norm function normalizes a 1-dimensional array or CImage object by scaling all its elements to make their sum equal to 1.0.

Whereas this function operates on a pure (indexed) array, the slightly slower normn function operates on a general table that may be a multi-dimensional array or contain a mixture of numbers, strings, named keys, and sub-tables.

Syntax

new_table = norm( table )

table is a 1-dimensional array or CImage object.

new_table is the returned table.

Examples

The following script creates a Gaussian normal population of 10,000 numbers with the area under the curve normalized to 1.0.

t = norm( gaussdev(10000) )

-- create a table of 10,000 values and normalize it

The next script normalizes a CImage.

V = AttachView( "CImageView" )	-- attach the topmost image window
Assert( V and V:Count() > 0 )	-- make sure an image window is on top
norm( V:GetImage() )	-- normalize the CImage
