Method Details

conjugate

public MatrixStore<N> conjugate()

Description copied from interface: MatrixStore

Returns the conjugate transpose of this matrix. The conjugate transpose is also known as adjoint matrix, adjugate matrix, hermitian adjoint or hermitian transpose. (The conjugate matrix is the complex conjugate of each element. This NOT what is returned here!)

See Also:

• VectorSpace.conjugate()

doubleValue

public double doubleValue(int aRow,
 int aCol)

Description copied from interface: Access2D

Extracts one element of this matrix as a double.

Parameters:

aRow - A row index.

aCol - A column index.

Returns:

One matrix element

doubleValue

public double doubleValue(long anInd)

get

public N get(int aRow,
 int aCol)

multiply

public void multiply(Access1D<N> right,
 TransformableRegion<N> target)

multiply

public MatrixStore<N> multiply(double scalar)

Returns:

this * scalarMultiplicand.

multiply

public MatrixStore<N> multiply(MatrixStore<N> right)

Parameters:

right - The multiplicand

Returns:

this * multiplicand.

multiply

public MatrixStore<N> multiply(N scalar)

Returns:

this * multiplicand.

multiplyBoth

public N multiplyBoth(Access1D<N> leftAndRight)

Description copied from interface: MatrixStore

Assumes [leftAndRight] is a vector and will calulate [leftAndRight]^H[this][leftAndRight]

Specified by:

multiplyBoth in interface MatrixStore<N extends Comparable<N>>

Overrides:

multiplyBoth in class AbstractStore<N extends Comparable<N>>

Parameters:

leftAndRight - The argument vector

Returns:

A scalar (extracted from the resulting 1 x 1 matrix)

premultiply

public ElementsSupplier<N> premultiply(Access1D<N> left)

Description copied from interface: MatrixStore

The premultiply method differs from multiply in 3 ways:

1. The matrix positions are swapped - left/right.
2. It does NOT return a MatrixStore but an ElementsSupplier instead.
3. It accepts an Access1D as the argument left matrix.

Parameters:

left - The left matrix

Returns:

The matrix product

supplyTo

public void supplyTo(TransformableRegion<N> receiver)

toScalar

public Scalar<N> toScalar(int row,
 int col)

Description copied from interface: Matrix2D

Extracts one element of this matrix as a Scalar.

Parameters:

row - A row index.

col - A column index.

Returns:

One matrix element as a Scalar.

transpose

public MatrixStore<N> transpose()

Returns:

A transposed matrix instance.
