Public Methods

Method	Description
Add ( Matrix a, Matrix b ) : Matrix	Add two matrixes together, producing a third.
Copy ( Matrix source, Matrix target ) : void	Copy the source matrix to the target matrix. Both matrixes must have the same dimensions.
DeleteCol ( Matrix matrix, int deleted ) : Matrix	Delete a single column from a matrix. A new matrix, with the delete is returned.
DeleteRow ( Matrix matrix, int deleted ) : Matrix	Delete a row from a matrix. A new matrix, with the row deleted, is returned.
Divide ( Matrix a, double b ) : Matrix	Divide every cell in the matrix by the specified number.
DotProduct ( Matrix a, Matrix b ) : double	Compute the dot product for two matrixes. Note: both matrixes must be vectors.
Identity ( int size ) : Matrix	Create an identiry matrix, of the specified size. An identity matrix is always square.
Multiply ( Matrix a, Matrix b ) : Matrix	Multiply two matrixes.
Multiply ( Matrix a, double b ) : Matrix	Multiply every cell in the matrix by the specified value.
Subtract ( Matrix a, Matrix b ) : Matrix	Subtract one matrix from another. The two matrixes must have the same number of rows and columns.
Transpose ( Matrix input ) : Matrix	Transpose the specified matrix.
VectorLength ( Matrix input ) : double	Calculate the vector length of the matrix.
