Here is a basic heatmap function.

EDIT: Updated, round(1) replaced by round(2) in order to avoid hidden dependencies to mathlib.dll via EFI plugin.

Nice! It reminds me of this other heat map. See the video. There is a download link of the javascript on the youtube description.

Yes, the example is one of the category "how to solve a problem in SMath that I would not have without SMath". Personally, I prefer gnuplot or matlab for real plotting, although the XY-Plot-Plugin is quite fine for the use cases it can handle (heat map not being among them). I intend to use the function for visualization of matrix population, e.g. for the stiffness matrix of a finite element model.

Very nice,

there's the round() function to fix (round(2) instead of the inexistent round(1))


best regards,

round(1) is from the mathlib.dll via EFI for SMath Studio plugin, which is pre-installed in the inofficial distribution ("SMath with plugins" wiki page).

Ok (The worksheet doesn't contains the EFI in the tag, so the notification does not appears)

I guess that the dependency finder is not aware of what the EFI plugin loads in the background. However, I changed the example to rely on round(1) only.
