Matrix transposed-matrix multiplication.

void mxMatMulVec(Mat* mat, Vec* b, Vec* out)

Matrix-vector multiplication.

void mxRealMulMat(real scalar, Mat* matrix, Mat* out)

Scalar-matrix multiply -- may be in-situ

void mxVecMulMat(Vec* b, Mat* mat, Vec* out)

Vector-matrix multiplication.

void mxTrMat(Mat* in, Mat* out)

Transpose matrix

void mxSwapRowsMat(Mat* mat, int i, int j, int lo, int hi)

Swaps rows i and j of matrix A upto column lim.

void mxSwapColsMat(Mat* mat, int i, int j, int lo, int hi)

Swap columns i and j of matrix A upto row lim.

void mxMatAddRealMulMat(Mat* mat1, Mat* mat2, real s, Mat* out)

Matrix-scalar multiply and add.

void mxVecAddRealMulMatMulVec(Vec* v1, real alpha, Mat* mat, Vec* v2, Vec* out)

Matrix-vector multiply and add.

void mxVecAddRealMulVecMulMat(Vec* v1, real alpha, Vec* v2, Mat* mat, Vec* out)
