SW_SURF draws a two dimensional plot using the patch function when the
figure is saved in .pdf format, it is saved as a vector image
Usage:
SW_SURF(C)
SW_SURF(X,Y,C,cLim,cMap)
Input:
X Matrix of x coordinates, dimensions are [nX nY].
Y Matrix of y coordinates, dimensions are [nX nY].
C Matrix to plot, dimensions are [nX nY].
cLim Color axis limits, if undefined the minimum and maximum values
C are taken as limits.
cMap Colormap, default is @jet.
maxPatch Maximum number of pixels that can be plotted using the patch()
function. Using patch for color plot can be slow on older
machines, but the figure can be exported afterwards as a vector
graphics, using the print() function. Default is 1000.
Change of the color axis after plotting is not possible, replot is
necessary.
