Constructor Detail

SliceMatrixF

public SliceMatrixF(MatrixF matrix,
                    int row,
                    int col,
                    int numRows,
                    int numCols)

Creates a SliceMatrixF based on the indicated matrix whose upper left corner is at (row, col) of that matrix and whose size is numRows x numCols.

Parameters:

matrix - the matrix we are to take a slice of

row - the row in matrix in which the slice is to begin

col - the column in matrix in which the slice is to begin

numRows - the number of rows that the slice should be

numCols - the number of columns that the slice should be

Method Detail

get

public float get(int row,
                 int col)

Description copied from class: MatrixF

Returns a particular element of this matrix

Specified by:

get in class MatrixF

Parameters:

row - the index of the row of the element to return

col - the index of the column of the element to return

Returns:

the element at the indicated row and column

MatrixF.put(int, int, float)

put

public void put(int row,
                int col,
                float value)

Description copied from class: MatrixF

Updates a particular element of this matrix

Specified by:

put in class MatrixF

Parameters:

row - the index of the row of the element to update

col - the index of the column of the element to update

value - the new value for the indicated element

emptyMatrix

public MatrixF emptyMatrix(int numRows,
                           int numCols)

Description copied from class: MatrixF

Returns a new empty matrix of the indicated dimensions. If a specific implementation associated with the receiver can be used with these dimensions, then such is used; otherwise a general matrix implementation will be used.

Specified by:

emptyMatrix in class MatrixF

Returns:

a new empty matrix of the indicated dimensions
