asCollectable2D

default <NN extends Number,R extends Mutate2D.Receiver<NN>> Access2D.Collectable<NN,R> asCollectable2D()

byteValue

default byte byteValue(long index)

Specified by:

byteValue in interface Access1D<N extends Number>

byteValue

default byte byteValue(long row,
                       long col)

columns

default ColumnView<N> columns()

doubleValue

default double doubleValue(long index)

Specified by:

doubleValue in interface Access1D<N extends Number>

doubleValue

double doubleValue(long row,
                   long col)

Extracts one element of this matrix as a double.

Parameters:

row - A row index.

col - A column index.

Returns:

One matrix element

elements

default ElementView2D<N,?> elements()

Description copied from interface: Access1D

Returns an Iterable of ElementView1D. It allows to iterate over the instance's element "positions" without actually extracting the elements (unless you explicitly do so).

Specified by:

elements in interface Access1D<N extends Number>

floatValue

default float floatValue(long index)

Specified by:

floatValue in interface Access1D<N extends Number>

floatValue

default float floatValue(long row,

get

default N get(long index)

Specified by:

get in interface Access1D<N extends Number>

get

N get(long row,
      long col)

intValue

default int intValue(long index)

Specified by:

intValue in interface Access1D<N extends Number>

intValue

default int intValue(long row,
                     long col)

longValue

default long longValue(long index)

Specified by:

longValue in interface Access1D<N extends Number>

longValue

default long longValue(long row,
                       long col)

rows

default RowView<N> rows()

shortValue

default short shortValue(long index)

Specified by:

shortValue

default short shortValue(long row,
                         long col)

toRawCopy2D

default double[][] toRawCopy2D()
