In a new worksheet

gcd(a,b);
                               1

Why is maple computing this? It does it for a lot of functions and I never know if it is giving the correct results. a and be are not defined. I'd expect it to just return gcd(a,b).

I put it in formulas but I never know if it is simplifying before computing. I have no idea why. Maple never did this stuff until I upgraded.

matrixplot(A, style=surface,axes=normal, lightmodel=light2, labels=["n","d","C"], heights=histogram, gap=0.00000000000000000001, colorscheme=["xyzcoloring", (x,y,z)->x*y*z]);

For a matrix about 500x70. It doesn't seem that it should crap out with such a small matrix to plot. Maple seems to be slow in general even small plotting of 3D things. Specifically I'm talking about rendring and rotating.

Just want labels but no axes. Also seems with axes=none sometimes I get wierd artifacts in the surfacewireframe where the wireframe is some wierd color. If I set the axes to normal it goes away and then usually it is ok. Sometimes half the graph is colored this way. It is with MatrixPlot.

How does one set the size of a 3D plot? I get tired of dragging it's size when it resets it to the default size. size=[w,h] does not work with plot3d.

matrixplot(A, style=surfacewireframe,heights=histogram);

when A has zero values they are graphed, is there any way to not have them show? Choose any matrix for A I just want to see non-zero elements.

Also when looking down on the 3d graph I'd like the tops of the histogram cells to be colored as if I'm looking at a 2d plot. When I do it now I can't tell any difference between any of the cells. This looks to be a lighting issue I suppose. There is some variation but it is very difficult to tell. Some light settings work better than others. Z-Hue seems to be the best but still a little washed out.
