MatrixPlot

MatrixPlot[m]
generates a plot that gives a visual representation of the values of elements in a matrix.

MORE INFORMATION

MatrixPlot[m] by default arranges successive rows of m down the page, and successive columns across, just as a matrix would normally be formatted.

MatrixPlot by default displays zero values as white, with negative values tending to be bluish and positive values reddish.

MatrixPlot has the same options as ArrayPlot, with the following changes:

	ClippingStyle	Automatic	how to show clipped values
	Frame	True	whether to draw a frame around the plot
	FrameTicks	All	what ticks to include on the frame
	MaxPlotPoints	Automatic	the maximum number of points to include

PlotRange->r specifies that only those a_ij between -r and +r should be shown.

With the default setting ColorFunctionScaling->True, scaling is done based on a mixture of relative value and ranking for each matrix element. The final scaled value always lies between 0 and 1, with scaled value 0.5 corresponding to matrix element value 0.

With the default setting MaxPlotPoints->Automatic, sufficiently large or sparse matrices are downsampled so that their structure is visible in the plot generated by MatrixPlot.

MatrixPlot works with SparseArray objects.
