wrap

static <N extends Number> Access2D<N> wrap(N[][] target)

wrapAccess2D

@Deprecated
static Access2D<Double> wrapAccess2D(double[][] target)

Deprecated. v45 Use wrap(double[][]) instead

wrapAccess2D

@Deprecated
static <N extends Number> Access2D<N> wrapAccess2D(N[][] target)

Deprecated. v45 Use #wrap(N[][]) instead

asCollectable2D

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

columns

default Iterable<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>

get

default N get(long index)

Specified by:

get in interface Access1D<N extends Number>

get

N get(long row,
      long col)

rows

default Iterable<RowView<N>> rows()

toRawCopy2D

default double[][] toRawCopy2D()
