Multiplies matrix m1 times Vector v1 and places the result
into this vector (this = m1*v1).
|
void |
GVector.mul(GVector v1,
GMatrix m1)
Multiplies the transpose of vector v1 (ie, v1 becomes a row
vector with respect to the multiplication) times matrix m1
and places the result into this vector
(this = transpose(v1)*m1).
|
void |
GMatrix.mulTransposeBoth(GMatrix m1,
GMatrix m2)
Multiplies the transpose of matrix m1 times the transpose of matrix
m2, and places the result into this.
|
void |
GMatrix.mulTransposeLeft(GMatrix m1,
GMatrix m2)

places the result into this.
|
void |
GMatrix.mulTransposeRight(GMatrix m1,
GMatrix m2)

Sets the value of this matrix to the matrix difference of itself
and matrix m1 (this = this - m1).
|
void |
GMatrix.sub(GMatrix m1,
GMatrix m2)
Sets the value of this matrix to the matrix difference
of matrices m1 and m2 (this = m1 - m2).
|
int |
GMatrix.SVD(GMatrix U,
GMatrix W,
GMatrix V)
Finds the singular value decomposition (SVD) of this matrix
such that this = U*W*transpose(V); and returns the rank of
this matrix; the values of U,W,V are all overwritten.
|
void |
GVector.SVDBackSolve(GMatrix U,
GMatrix W,
GMatrix V,
GVector b)
Solves for x in Ax = b, where x is this vector (nx1), A is mxn,
b is mx1, and A = U*W*transpose(V); U,W,V must
be precomputed and can be found by taking the singular value
decomposition (SVD) of A using the method SVD found in the
GMatrix class.
|
void |
