Method Details

maskElements

public static MatrixMask maskElements(int rows,
 int cols,
 boolean[][] mask)

Mask individual elements of the given matrix.

maskElements

public static MatrixMask maskElements(int rows,
 int cols,
 int[] i,
 int[] j)

Mask individual elements of the given matrix at the specified coordinates.

This uses a sparse representation internally, which is more efficient for large matrices with few masked elements.

maskRows

public static MatrixMask maskRows(int rows,
 int cols,
 boolean[] rowMask)

Mask whole rows of the given matrix.

maskColumns

public static MatrixMask maskColumns(int rows,
 int cols,
 boolean[] columnMask)

Mask whole columns of the given matrix.

hasColumnMask

public boolean hasColumnMask()

Indicate if this mask has any column-wise masking.

hasRowMask

public boolean hasRowMask()

Indicate if this mask has any row-wise masking.

hasElementMask

public boolean hasElementMask()

Indicate if this mask has any element-wise masking.

isRowMasked

public boolean isRowMasked(int row)

isColumnMasked

public boolean isColumnMasked(int column)

isMasked

public boolean isMasked(int row,
 int column)

inverted

public MatrixMask inverted()

Invert the mask of this matrix, allowing access to the previously masked elements.
