applyChain

const float *applyChain(idx_t n, const float *x) const

Performs linear transformation on feature vector data.

Index::idx_t n: number of feature vectors in the training dataset.

const float *x: feature vector data.

N/A

Feature vector data after linear transformation.

• The value of n cannot be greater than 1e9.
• The x must be a non-null pointer with a length of dim x n. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown.
