void |
GMatrix.add(GMatrix m1)
Sets the value of this matrix to sum of itself and matrix m1.
|
void |
GMatrix.add(GMatrix m1,
GMatrix m2)
Sets the value of this matrix to the matrix sum of matrices m1 and m2.

GMatrix.copySubMatrix(int rowSource,
int colSource,
int numRow,
int numCol,
int rowDest,
int colDest,
GMatrix target)
Copies a sub-matrix derived from this matrix into the target matrix.
|
boolean |
GMatrix.epsilonEquals(GMatrix m1,
double epsilon)
Returns true if the L-infinite distance between this matrix
and matrix m1 is less than or equal to the epsilon parameter,
otherwise returns false.
|
boolean |
GMatrix.epsilonEquals(GMatrix m1,
float epsilon)
Deprecated.
Use epsilonEquals(GMatrix, double) instead
|
boolean |
GMatrix.equals(GMatrix m1)
Returns true if all of the data members of GMatrix m1 are
equal to the corresponding data members in this GMatrix.
|
void |
GMatrix.get(GMatrix m1)
Places the values in the this GMatrix into the matrix m1;
m1 should be at least as large as this GMatrix.
|
void |
GMatrix.invert(GMatrix m1)
Inverts matrix m1 and places the new values into this matrix.
|
int |
GMatrix.LUD(GMatrix LU,
GVector permutation)
LU Decomposition: this matrix must be a square matrix and the
LU GMatrix parameter must be the same size as this matrix.
|
void |
GVector.LUDBackSolve(GMatrix LU,
GVector b,
GVector permutation)
LU Decomposition Back Solve; this method takes the LU matrix
and the permutation vector produced by the GMatrix method LUD
and solves the equation (LU)*x = b by placing the solution vector
x into this vector.
|
void |
GMatrix.mul(GMatrix m1)
Sets the value of this matrix to the result of multiplying itself
with matrix m1 (this = this * m1).
|
void |
GMatrix.mul(GMatrix m1,
GMatrix m2)
Sets the value of this matrix to the result of multiplying
the two argument matrices together (this = m1 * m2).
|
void |
GVector.mul(GMatrix m1,
GVector v1)
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)
Multiplies the transpose of matrix m1 times matrix m2, and
places the result into this.
|
void |
GMatrix.mulTransposeRight(GMatrix m1,
GMatrix m2)
Multiplies matrix m1 times the transpose of matrix m2, and
places the result into this.
|
void |
GMatrix.negate(GMatrix m1)

GMatrix.sub(GMatrix m1)
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.
