Detailed Description

Linear algebra utility functions, generally performed on matrices or vectors.

This class is used to update the weightVectors matrix according to the simple update rule as discussed by Rosenblatt:

if a vector x has been incorrectly classified by a weight w, then w = w - x and w'= w'+ x

where w' is the weight vector which correctly classifies x.

inline

Return the matrix's allocated memory pointer, unless the matrix is using its internal preallocated memory, in which case we copy that and return a pointer to the memory we just made.
