I have a program that may call Compiler:-Compile to speed up the calculations, but after the program terminates the DLL that was generated still exists on disk. Every time I call on the program, I create a new DLL without deleting it. If I keep calling my program, the disk will get full of temporary DLL's until the disk gets full. I know how to delete using FileTools:-Remove, but I get the "permission denied" error message. I assume that it is because Maple 10 is still using the DLL, so how do I get Maple to free the DLL so that I can delete it?

Suppose I have the vertices of a polyhedron in a matrix and wanted to draw a stick model of it as a plot. I need to be able to specify the color of each edge. What's the best way to go about this? I've tried creating an array of pointplot3d's with connect=true and grouping them together with the display command but that doesn't seem to allow me to select colors for each edge. As an example, if you could show me how to make a line from

All: I am comparing examples of Lower Sums, Upper Sums, and Random Partitioned Riemann Sums. For the lower and upper sums, the leftbox and rightbox commands produce satisfactory box shading results, green RGB(.7,.9,.7). For example: leftbox(x,x=0..2, 4); However, I can't get the RiemannSum command to shade. I have used all of the tricks that I know of and all that I can do is change the color of the outline of the boxes. For example: RiemannSum(x, x = 0..2, partition=2, method=lower, output=plot, showarea=false, outline=false, boxoptions=[color=black, thickness=2], thickness=3, title="", tickmarks=[5,6], labels=["",""], scaling=unconstrained, refinement = random, functionoptions = [legend="", color=RED], partition=random[.75]);

I need to evaluate expression

sum((sum((sum((1-p)^i/(a[1]*i+a[1]+a[2]*j+a[2]+a[3]*k+a[3]), i = 0 .. infinity))*(1-p)^j, j = 0 .. infinity))*(1-p)^k, k = 0 .. infinity).

A straightforward evalf(subs(a[1] = .4, a[2] = .1, a[3] = .5, p = 1/3, %)) is too too slow. Are there any faster solutions? Thanks in advance.

Every time I try to make an underscore _ in Maple, I am forced into a subscript. Hence, I cannot enter commands such as dperiodic_sols from the DEtools list into my program. Thank you.

Hi, Does anyone know a way to modify the number of rows and columns in a spreadsheet in Maple? For example, if I wanted a 500 by 2 spreadsheet, how would I go about getting it? Right now, the spreadsheet maxes out at 100 rows. Thanks in advance for your help. -Evan

Im looking for help with a question, i need to produce a procedure using both False Position and Newton-Raphson methods' here is the queston; Write a Maple procedure to find the root (answer) of a function (fun) to a specified accuracy (acc_nr) using a combination of the methods of false position and Newton-Raphson. Your procedure should start with an interval ([left,right])in which the root lies and first carry out sufficient iterations of the false position method to find an estimate of the root (to an accuracy of acc_fp, a much larger number than acc_nr). This estimate should then be used as the starting value for the Newton-Raphson method which should then find the root to the final specified accuracy (acc_nr).

We have an expression p*(-1+p)*hypergeom([1, 1], [2], 1-p)*hypergeom([1], [], 2-p), which can be simplified to p*ln(p)/(-1+p), but how it can be simplified to p*hypergeom([1,1],[2],1-p) in Maple? Thanks.

Looking for a direct link to download Maple (trial or full version)

I would like to copy Maple results and insert them in text documents (e. g. MS-Word). I highlighted the Mple result and copied it with the context menu (strg+c, Windows). Following I pasted it with the context menu in a Word Document. Unfortunately the pasted image was very fuzzy (actually unreadable). Is there any other method to copy Maple outcomes quickly in text documents? Thanks Dirk

Why does Maple not substitute the value for y[1] in the result? subs(m=3,y[1]=2,sum(r[i]*y[i],i=1..m));%; I assume that the values were substituted in sum() but subs() does not execute sum(). Accordingly there is at the timepoint of substitution no y[1] in sum()? Thanks Dirk

hi. I am trying to make a list of 2 by 2 matrices with entries from Zp. (for the moment p=3) I managed to make the matrices, but I can't for the life of me get them over in a list. This is the code I have written, and I would love some help, or an alternative solution. E := Matrix([[k, i], [j, l]]); for k from 0 to p-1 do for i from 0 to p-1 do for j from 0 to p-1 do for l from 0 to p-1 do E; print(E); end do ; end do ; end do ; end do;

What is the RGB color designation for the default green shading color that Maple uses? For example, the green shading color generated when using the command with(student); leftbox(x,x=0..2); Thanks all.

I am trying to plot a graph of two functions and fill between the two lines. The code I have seems to work as I type it, but when I remove the output and re-execute it completely ignores the 'white' fillings. Here is the code I have so far: restart:with(plots): First I assign to u and v to the equations. u:=0.21e-1*x^3-0.947e-1*x^2-1.77*x+1.79; v:=-0.451e-2*x^3-0.473e-1*x^2+.243*x+4.74; Then I plot the functions and find the intercepts. plot([u,v],x=-8..11,y=-9..7,color=[blue,green]); inters:=fsolve(u=v); x_int_u:=fsolve(u); x_int_v:=fsolve(v); Plot again and shade the regions of interest.

I have an exam in vector analysis soon, and it happens quite often we're supposed to parametrize the surface of as solid. Is there a way to get maple to plot the solid so it's simpler to visualize the current situation? Suppose for example that E is the solid defined by x^2+y^2+z^2=<>a^2 with a some constant and =<> means greater than or equal to. Suppose S is the boundary-surface of E. How do I plot S in the easiest way? It's for use for an exam so time is precious.
