standardizetransform

Standardize the test dataset using values computed by 'standardize' function.

Syntax

scaled_X = standardizetransform(parameters,X)

Inputs

X: Input data to be standardized.; Type: double; Dimension: vector | matrix
parameters: Struct containing values such as mean and standard deviation to be used to standardize test data. It is output from 'standardize' function.; Type: double | integer; Dimension: struct

Outputs

scaled_X: Standardized input records.; Type: integer; Dimension: vector | matrix

Example

Usage of standardizetransform

X = [1, -1, 2;
     2, 0, 0;
     0, 1, -1];
X_test = [-1, 1, 0];
[X_scaled, parameters] = standardize(X);
X_test_scaled = standardizetransform(parameters, X_test);
