pcatransform

Transforms target values for the test data points using parameters computed by pcaFit function.

Attention: Available only with Twin Activate commercial edition.

Syntax

outputs = pcatransform(parameters,X)

Inputs

X
Test data.
Type: double
Dimension: vector | matrix
parameters
Output of agglomerativeFit function.
Type: struct

Outputs

outputs
Transformed output for the test data.

Example

Usage of pcatransform with options

X = [-1, -1; -2, -1; -3, -2; 1, 1; 2, 1; 3, 2];
options = struct;
options.n_components = 2;
parameters = pcafit(X, options)
outputs = pcatransform(parameters, X);
