draw scaled shadow image of a matrix
[x colorMapNew]=eshadois(matrix[,colorMap[,legendOrientation[,legendScale]]])
matrix :
matrix for image
colorMap :
define own colormap
legendOrientation :
side of the image where the legend appears
character ‘s’(south),’n’(north),’w’(west) or ‘e’(east)
(default orientation is east)
legendScale :
scale vector of legend [start step end]
special cases of scale vector are
if start=0 and end=0 then autorange=on
if step=0 then autoscale=on
(default scale vector=[0 0 0])
x :
scaled shadow image matrix
colorMapNew :
colormap of shadow image
special case of return parameters
if the return parameters are used then no output
