Images and contours in Igor Pro

A two-dimensional wave can be drawn as an image or as contour lines.

Function ShowMatrix(WAVE m)
    DoWindow/K MatrixView
    NewImage/N=MatrixView m

    ModifyImage $NameOfWave(m) ctab={*, *, Rainbow, 0}
    ModifyGraph mirror=2, tick=2

    AppendMatrixContour m
    ModifyContour $NameOfWave(m) autoLevels={*, 8, 0}
    ColorScale/A=RC/E image=$NameOfWave(m), "amplitude"
End

How it works

1. NewImage opens a window; AppendImage adds to the current one.
2. ModifyImage ctab= picks the color table and its range.
3. AppendMatrixContour draws the same matrix as contour lines.
