Detailed Description

Principal component analysis. Note that this method is relatively efficient and precise when a low number of components is required. It uses fixed point numbers internally so it may fail on large inputs due to overflow.

Note

D - shared3p protection domain

Supported types - float32 / float64

Parameters

X	- data matrix where the columns are variables
n_components	- how many components to compute
iterations	- how many iterations to run the algorithm
returnValues	- indicates which results to return. Use bitwise or if you want multiple results.

Returns

PCAResult structure

Leakage

None
