comment Steady State Numerical Solution of Heat Diffusion Equation in 2D
You can cook up a boundary condition without the corner discontinuity issue and you still get that same error message.

for best performance use no formatting at all. Write out raw binary and read into mathematica with ReadList

comment Dot product for lists
@Guesswhoitis. Can this be done with inner? I thought so too, but cant make it work.

comment Is it possible that we can use “+” to add two vectors in polar form?
Sean, if you made it work go ahead and post the solution as an answer. (Otherwise the question will keep popping up as unanswered)

comment Using PlotRange to cut off outlying points
is is bad wording regardless of whether its also bug ( or an abandoned feature perhaps? ). Liam, can you include an example of the actual syntax you tried that produces that error in the question.

comment reset the value of a variable
just do this: rankboard[[j, i]] = (j*10*row1[i]/max1) + ((1 - j)*10*row2[i]/max2); without redefining row1[i].

comment Deleting multiple elements from a list
Interesting approach. There is no reason for the l=l; is there?

comment Better to use loop or function when populated list?
the 1.5 is surely 1+k from randomA[[0 ]] + k * randomB [[ 0 ]]. I dont see how you get there with this version of the code though.

comment Better to use loop or function when populated list?
each pick has a 1 in 10 chance of duplicating the prior one (or nearly so..)

comment Why do Mathematica list indices start at 1?
The reason for zero indexing becomes perfectly obvious as soon as you find yourself doing index arithmetic.With mathematica we practically never need to resort to such arithmetic, so there is no reason to make the otherwise unnatural choice of counting from zero.

comment ListPlot with checkboxes
Just by the way, this does throw an error (w/v9) if you un-check all the boxes. Just a minor annoyance.

comment ListPlot with checkboxes
this is I think better than the accepted answer to the dup. -- If this question gets closed you should move this over there.

@wxffles good point, I didn't realize you could do specify a Scaled FontSize.

comment Place a small gap between axes and plot?
that's what your ListPlot[{}, .. does. Just an axis with no data. In v9 this throws an error "ListPlot called with 0 arguments" . This tricks it into working : ListPlot[{""}, ... ]

comment Place a small gap between axes and plot?
yes you can. Actually the other issue I had in v9 ListPlot does not like an empty list. You can give it an out of range point though to get an empty plot.

comment Logarithmic x-axis for ListPlot?
of course the requested power law interval is not logarithmic. You ought to edit the question or title to clarify what you mean.
