public class CSparseWin

extends JFrame

As we perform linear algebra operations on a CSparse matrix, this window displays the changing sparsity pattern and other information. The pixels represent consecutive k × k submatrices, where k ≥ 1 is chosen so the whole matrix fits in the window. Each pixel is colored in grayscale by what proportion of the k² entries of the submatrix are non-zero. White means the whole submatrix is zero; black means its entries are all non-zero.

Displaying a CSparseWin slows down the computation. Minimizing the window eliminates the slowdown.

Constructor Detail

CSparseWin

public CSparseWin(CSparse A,
                  String title)

Method Detail

refresh

public final void refresh()

Calls repaint() on the main panel.

setCorner

public final void setCorner(int corner)

Says the upper-left block 0 ≤ i, j < corner should be assumed to be diagonal. The diagonal pixels are painted black, because a grayscale of k/k² = 1/k may be too faint.

setNote

public final void setNote(String note)

Sets a note at the top of the screen.

setYellow

public final void setYellow(int a,
                            int b)

Sets columns a ≤ j < b to be solid yellow. If a ≥ b, the feature is turned off.
