Is there a way to specify different colors for different output variables? For example, if x,y, and z appear in the entire document as variables, I want x to be red, y to be blue, and z to be green whenever an output is displayed.


One way is coloring a surface on both sides. We build equidistant surface with very small radius and stain the equidistant surface in color different from the color of the original surface.
Examples coloring of surfaces on both sides.  Radius equal to abs (0.0001).

i would like to plot a cube with the color given by a 3 variables functions (a way to plot in R^4)

in this way the cube is the domain of the functions, its color is the value of the function, i would like to put in evidence the max min of such function

but the command that i tried to use does not work:

plots[display](plotools([cuboid]([0,0,0],[1,1,1]),trasparency=.7,colorscheme["xyzcoloring",proc(x,y,z) option operator , arrow; x^2 + y^2 - z^2 end(proc)])

thanks for your help, anna rita

Hi There:

i have big expressions with many variables of the form (say)  Q__T(t). I would like to simplify my visual parsing of them.

I was wondering if there is a way to tell maple to print particular symbols/variables in specific colors (something akin to what the Physics package does). I.e. I would imagine saying something like:

setup_print_color(Q__T(t), "red");

and then every time Q__T(t) would come up, it would be printed in my desired color.

is this easily possible? I've looked through docs and this site, but can't find any info.




using worksheet mode, is there a way to automatically color any comments after (#) with a different color than the default red?

I have been using Maple for years and did not need to significantly document or comment on my worksheets before because I only needed to share my worksheets with close collegues who have a lot of experience with Maple too. However, now I need to share my code with a general audience that might not be a Maple user. So I need to add enough comments after each line, and I have been manually changing the color of comments after the # to green to give the reader the indication that this is a comment and not part of the code, like this for example:



f:=(x,y)->sin(sqrt(x^2+y^2))/sqrt(x^2+y^2); # Define f as a function of the variables x and y

proc (x, y) options operator, arrow; sin(sqrt(x^2+y^2))/sqrt(x^2+y^2) end proc


df:=(x,y)->eval(diff(f(a,y),a),a=x); # Define df as the partial derivative of f with respect to x

proc (x, y) options operator, arrow; eval(diff(f(a, y), a), a = x) end proc


df(1,3); # Evaluate df at x=1, y=3






It would be great if Maple can automatically color comments like typical editors do. Is this possible? if not, does anyone have an advice for a nice easy way to add proper documentation to worksheets?

Dear Maple Users

I am mainly in favor of the new rules concerning subscripts. Using Ctrl+-- (double underscore) it is pretty straight forward to get a literal subscript and it displays much better in the palette Variables than was the case i Maple 16. Also the purple coloring of a variable containing a literal subscript makes sense, because it can be distinguished from the usual subscript (now Ctrl+shift+-). Good that you can remove the coloring in the View Menu (Atomic Variables...

Is it possible to paint in black and white colors the cells of 5x5 grid so that each 3x3 square contains exactly 5 black cells and  each 2x4 rectangle (vertical or horisontal) contains exactly 4 black cells? How to answer this with Maple?
