[Plplot-devel] Possible bug in matrix initialization

[Alan W. I. <ir...@be...>]

I have been struggling with resetting the cmap1 to default values for tcl.
Turns out my problems were due to the following construct which I thought
should work to initialize the matrix.

matrix l f 6  = {0.5, $midpt, $vertex, $vertex, $midpt, 0.5}

This silently fails by sticking zeroes everywhere there is a variable
reference (i.e., all the interior points) even though the variables have
previously been set.  Isn't this a bug? Shouldn't the variables just be
replaced by their values?

I worked around this by using

l 1 = $midpt
l 2 = $vertex

etc., in x08.tcl,

but I don't think this workaround should be necessary.
