†Multiple a Matrix by its Transpose P[m][m] = M[m][n] * MT[n][m]
|
ViXL_DLL_API int _vxMatMulMbyMT( const vector<vector<<double>> &Matrix, vector<vector<<double>> &Product );
Populates the vector Product, with Matrix multiplied by its transpose, as P[m][m].
|
vxMatMulMbyMT(const Matrix &_Matrix );
Matrix = m rows x n columns
Returns product of Matrix multiplied by its transpose, as m rows x m columns (square). |
†Multiple Matrices, M1 by Transpose M2 Multiply the matrix Mat_1 by the transpose of the matrix Mat_2. The number of columns in Mat_1 must be equal to the number of columns in Mat_2. Populates the vector Product, with the result of the multiplication, as P[m][j] = M1[m][n] * M2T[j][n]
|

Populates the vector Product, with the result of matrix Mat_1 multiplied by the transpose of matrix Mat_2, as P[m][j]. |
vxMatMulM1byM2T(const Matrix &_Mat_1, const Matrix &_Mat_2 );
Mat_1 = m rows x n columns Mat_2 = j rows x n columns
Returns product of Mat_1 multiplied by the transpose of Mat_2, as m rows x j columns.
|
†Multiple Matrices, Transpose M1 by M2 P[n][j] = M1 T[m][n] * M2[m][j]
|
ViXL_DLL_API int _vxMatMulM1TbyM2( const vector<vector<<double>> &Mat_1, const vector<vector<<double>> &Mat_2, vector<vector<<double>> &Product );
Populates the vector Product, with the result of the transpose of matrix Mat_1 multiplied by matrix Mat_2, as P[n][j]. |
vxMatMulM1TbyM2(const Matrix &_Mat_1, const Matrix &_Mat_2 );
Mat_1 = m rows x n columns Mat_2 = m rows x j columns

|
†Multiple Transpose of Matrix by Vector P[n] = MT[m][n] * V[m]
|
ViXL_DLL_API int _vxMatMulMTbyVector( const vector<vector<<double>> &Matrix, const vector<double> &Vector, vector<<double> &Product );
Populates vector Product, of length equal to Matrix columns; or NULL on error.
|
vxMatMulMTbyVector(const Matrix &_ Matrix, const Matrix &_ Vector );
Mat_1 = m rows x n columns Vector = m rows x 1 columns
Returns product of the transpose of Matrix multiplied by Vector, as n rows x 1 column.
|
†Compute the Trace of a Matrix |
ViXL_DLL_API double _vxMatrixTrace( const vector<vector<<double>> &Matrix );
Returns the sum of the diagonal elements.
|
vxMatrixTrace(const Matrix &_Matrix );
Matrix = m rows x n columns
Returns the sum of the diagonal elements.
|
†Pseudo-Inverse Matrix Solver
|
ViXL_DLL_API int _vxPseudoInverseMat( const vector<vector<<double>> &Matrix, const vector<double> &Constraints, vector<double> &Solution );
Populates vector Solution, of length equal to Matrix n (columns), x = A-1 * w
|
vxPseudoInverseMat(const Matrix &_Matrix, const Matrix &_Constraints );
Matrix = m rows x n columns Constraint = m rows x 1 column
Returns solution vector, n rows x 1 column, for x = A-1 * w |
†Simultaneous Linear Equations Solver Calculates the solution vector for [m x m] array Matrix, and vector Constraints. The number of equations must be equal to the number of unknowns, and the length of Constraints must be equal the length m (rows) of Matrix. Populates vector Solution, of length equal to Matrix n (columns). V[m] = M[m][m] * X[m]
|
ViXL_DLL_API int _vxLinearEqSolver( const vector<vector<<double>> &Matrix, const vector<double> &Constraints, vector<double> &Solution );
Populates vector Solution, of length equal to Matrix m (columns), as V[m] = M[m][m] * X[m]
|
vxLinearEqSolver(const Matrix &_Matrix, const Matrix &_Constraints );
Matrix = m rows x m columns Constraint = m rows x 1 column
Returns solution vector, m rows x 1 column, as V[m] = M[m][m] * X[m] |
†Expected to be available in version v.0.4.x and later.
