- (optional) vector that the matrix can be multiplied against
left
- (optional) vector that the matrix vector product can be stored in
Notes
The blocksize of the returned vectors is determined by the row and column block sizes set with MatSetBlockSizes() or the single blocksize (same for both) set by MatSetBlockSize().
Notes
These are new vectors which are not owned by the Mat, they should be destroyed in VecDestroy() when no longer needed
