I am coloring the xy plane, by using a procedure(x,y) to assign color.
The procedure returns a number and color is assigned according to that number.
It works fine but I really want some of the points to be colored BLACK.
What numerical value do I use for BLACK? WHITE?

I am currently running a procedure that is taking up a lot of time in maple, I do not really need the whole output and would very much like Maple to run just for a set amount of time and output what it has done so far, how would I go about doing that?

I have written a module based Maple expressions to LaTeX converter which can handle the following nested (as given by `ToInert`

) inert types:

_Inert_RATIONAL, _Inert_COMPLEX, _Inert_NAME, _Inert_SUM, _Inert_PROD, _Inert_POWER, _Inert_SET, _Inert_LIST, _Inert_FUNCTION, _Inert_MATRIX, _Inert_VECTOR_COLUMN, _Inert_VECTOR_ROW, _Inert_TABLEREF.

As a somewhat cruel test example consider

expr := Matrix(2,2,(i,j) ->
-(-x)^(-i/2+c)*sin(x)^(-j)*(a+I*b)^((i-j)/2)
+f({-i,j})/g([-i,j])
+m[i,j]
);
newLatex:-Latex(expr);

which yields

Hi I can't find the error in this procedure that i have made , to calculate the maximum and return it for a particular function
here is the code :
mymax:=proc(h1,a1,b1) local t1; local maxi; maxi:=0; t1:=a1; for t1 to b1 do if h1(t1)>=maxi then maxi=h(t1); t1:=t1+0.1; fi; od; maxi; end;
h1 is the function
a1 and b1 are the [a1,b1] limit of the interval
Can you help me ;
thank you

I wonder if there are interesting newsletters and magazines (or even journals) devoted immediately to Maple using/programming. This link http://web.mit.edu/maple/www/plibrary/mtn.html
seems obsolete; can anyone help me create a list of useful subscriptions, RSS feeds included? Thank you all in advance.

In previous versions of Maple there was an abort/interrupt capability-one could hold down the command key and a period at the same time and eventually Maple would stop the calculation. (Mac worksheet interface). Now there is an interrupt icon which is frequently ignored by Maple. I am currently in an ∞ loop and cannot get out! Help!

hi
i want to know the maximum of this function ,
p := proc (x) options operator, arrow; min(piecewise(x <><><><><><><><><><><><><>

hi
let's look for the intersection of 2 functions
the first one
f1 := unapply(CurveFitting[Spline]([[1.55, 1], [1.6, 0], [1.65, 0], [1.7, 0], [1.75, 0], [1.80, 0], [1.85, 0], [1.9, 0], [1.95, 0]], x, degree = 1), x);
the second one
r := unapply(CurveFitting[Spline]([[1.55, 0], [1.6, 1], [1.65, 1], [1.7, 1], [1.75, 0], [1.80, 0], [1.85, 0], [1.9, 0], [1.95, 0]], x, degree = 1), x);
when we plot the 2 functions :
plot({f1(x), r(x)}, x = 1 .. 1.95, y = 0 .. 1, thickness = 3);
we see that there is 2 intersections
that are 1.575000000, RealRange(1.750000000, infinity)
but maple gives 1.575000000, 1.550000000, RealRange(1.750000000, infinity)

hi
lets say i have an array like this one
a:=[1.575000000, BottomProp, BottomProp,1.6, RealRange(1.750000000, infinity)];
i would like to have from this array only a:=[1.575000000,1.6];
how to do that
thank you

Hi I want to know whether it is possible to obtain the third order tensor (second derivative) and
also the higher order derivatives in Maple just as we can find the Jacobian. Then how?
For example, x=array(1..n): f:=[x[1]^2-2x[2], x[2]^3-3x[3]]: jac:=jacobian(f,x);
we can get the jacobian.
Can we get the second derivative (n by n by n matrix) and also the higher order derivatives. Thanks.

I have conmpleted a maplet application. It takes 45 seconds to initiate the application. I understand to speed up my application is to convert it into a module. Can someone show me how to convert my applicatioh into module.
Consider the application:
with(Maplets[Elements]):Hello:=Maplet(["Hello World!", Button("OK", Shutdown())]): Maplets[Display](Hello):
thanks in advance.

How would I plot the points of f[i,j,k] versus t[i,j,k] where i, j, and k are from -n to n?
Please let me know if you need clarification or further details as to what I'm trying to do.

Hello,
I have an equation to solve over the integers. I already know that there are an infinite number of solutions, but I would like to know how I can get Maple to reproduce my results. I used isolve, but it returned nothing. Is there a trick or way of phrasing the question to get Maple to solve the problem? Thanks
isolve((x+y+z)^3 = x*y*z)
I also tried (with the same results):
isolve((x+y+z)^3-x*y*z = 0)
The solution is obviously:
{0, n,-n}
or some permutation of this set. Note I would like to be able to solve this as if I had no guess!
Thank you.
