QPlot: qimsc

qimsc Plot 2D data as an image using lookup table

Help text:

qimsc(xywh, data) plots the data as an image using a lookup previously set by qlut. The color axis limits default to the min and max of the data.
qimsc(xywh, data, c0, c1) overrides those limits.
qimsc(xx, yy, data) or qimsc(xx, yy, data, c0, c1) specifies bin centers.
qimsc(data) or qimsc(data, c0, c1) sets xywh to (0,0)+(X,Y) as in qimage.

Example:

qfigure('qimsc', 3, 3);

xx = repmat([1:10], 10, 1);

yy = xx';

zz = cos(xx)+sin(yy);

cc = jet(100); % In octave, this inappropriately opens a native window

qlut(cc);

qimsc(xx, yy, zz);
