Enclosing class:

Matrix

public static class Matrix.GP2
extends Matrix

A simple, general-purpose implementation of a Matrix. Like all Matrices, a GP2 must be rectangular. (Also see the "1D" Vector.GP.)

Constructor and Description
GP2(Value[][] elts) Given a 2D Java array, [] [], of Values, construct a GP2, a Matrix.

Method Summary

Modifier and Type	Method and Description
Vector	elt(int r) Row 'r' (top-level element r) of 'this' Matrix; a sub-class of Matrix might be able to provide a more efficient version than this default.
Value	elt(int r, int c) Return the (r,c)-th of elts, forced.
int	nElts() The number of rows (top-level elements) in 'this' Matrix.
protected int	nEltsRaw(int r) Called in the rectangularity-check within Matrix.setNcols(int) if the constructor Matrix() was used; it need not be implemented (overridden) if Matrix(nC) was used.

Constructor Detail

GP2

public GP2(Value[][] elts)

Given a 2D Java array, [] [], of Values, construct a GP2, a Matrix.

Method Detail

nEltsRaw

protected int nEltsRaw(int r)

Description copied from class: Matrix

Called in the rectangularity-check within Matrix.setNcols(int) if the constructor Matrix() was used; it need not be implemented (overridden) if Matrix(nC) was used. See Matrix.nElts(int).

Overrides:

nEltsRaw in class Matrix

nElts

public int nElts()

Description copied from class: Matrix

The number of rows (top-level elements) in 'this' Matrix. Also see nCols().

Specified by:

nElts in class Matrix

elt

public Vector elt(int r)

Description copied from class: Matrix

Row 'r' (top-level element r) of 'this' Matrix; a sub-class of Matrix might be able to provide a more efficient version than this default. Also see elt(r,c). Note that elt(r).wt(c) is 1.0, ∀ c.

Overrides:

elt in class Matrix

elt

public Value elt(int r,
                 int c)

Return the (r,c)-th of elts, forced.

Specified by:

elt in class Matrix
