Method Details

applyBinOpp

public static CMatrix applyBinOpp(CsrCMatrix src1,
 CMatrix src2,
 BinaryOperator<CNumber> opp,
 UnaryOperator<CNumber> uOpp)

Applies the specified binary operator element-wise to the two matrices.

Parameters:

src1 - First matrix in element-wise binary operation.

src2 - Second matrix in element-wise binary operation.

opp - Binary operator to apply element-wise to the two matrices.

uOpp - Unary operator for use with binary operations which are not commutative such as subtraction. If the operation is commutative this should be null. If the binary operation is not commutative, it needs to be decomposable to one commutative binary operation opp and one unary operation uOpp such that it is equivalent to opp.apply(x, uOpp.apply(y)).

Returns:

A matrix containing the result from applying opp element-wise to the two matrices.

applyBinOpp

public static CMatrix applyBinOpp(CMatrix src1,
 CsrCMatrix src2,
 BinaryOperator<CNumber> opp)

Applies the specified binary operator element-wise to the two matrices.

Parameters:

src1 - First matrix in element-wise binary operation.

src2 - Second matrix in element-wise binary operation.

opp - Binary operator to apply element-wise to the two matrices.

Returns:

A matrix containing the result from applying opp element-wise to the two matrices.

applyBinOpp

public static CMatrix applyBinOpp(CsrCMatrix src1,
 double b,
 BinaryOperator<CNumber> opp,
 UnaryOperator<Double> uOpp)

Applies the specified binary operator element-wise to a matrix and a scalar.

Parameters:

src1 - First matrix in element-wise binary operation.

b - Scalar to apply elementwise using the specified operation.

opp - Binary operator to apply element-wise to the two matrices.

uOpp - Unary operator for use with binary operations which are not commutative such as subtraction. If the operation is commutative this should be null. If the binary operation is not commutative, it needs to be decomposable to one commutative binary operation opp and one unary operation uOpp such that it is equivalent to opp.apply(x, uOpp.apply(y)).

Returns:

A matrix containing the result from applying opp element-wise to the two matrices.

applyBinOpp

public static CMatrix applyBinOpp(CsrCMatrix src1,
 CNumber b,
 BinaryOperator<CNumber> opp,
 UnaryOperator<CNumber> uOpp)

Applies the specified binary operator element-wise to a matrix and a scalar.

Parameters:

src1 - First matrix in element-wise binary operation.

b - Scalar to apply elementwise using the specified operation.

opp - Binary operator to apply element-wise to the two matrices.

uOpp - Unary operator for use with binary operations which are not commutative such as subtraction. If the operation is commutative this should be null. If the binary operation is not commutative, it needs to be decomposable to one commutative binary operation opp and one unary operation uOpp such that it is equivalent to opp.apply(x, uOpp.apply(y)).

Returns:

A matrix containing the result from applying opp element-wise to the two matrices.

applyBinOppToSparse

public static CsrCMatrix applyBinOppToSparse(CMatrix src1,
 CsrCMatrix src2,
 BinaryOperator<CNumber> opp)

Applies an element-wise binary operation to a real dense and real sparse CSR matrix under the assumption that opp.apply(x, 0d) = 0d and opp.apply(0d, x) = 0d.

Parameters:

src1 - The first matrix in the operation.

src2 - Second matrix in the operation.

opp - Operation to apply to the matrices.

Returns:

The result of applying the operation element-wise to the matrices. Result is a sparse CSR matrix.
