I understand how Browse() works. Sometimes Maple crashes or fails for some programs. Is it possible to add print("here" ) into the the mla files in the library to identify why and where Maple fails?

Thanks

How do I simulate the follow stochastic differential equations. Thanks very much!

dx=x*(5-2*x-3*y-z)dt+5x*dB1(t);

dy=y*(4-*x-5*y-2z)dt+4y*dB2(t);

dz=z*(2-5*x-7*y-2z)dt+2z*dB3(t);

I want to plot the eigenvalues of a 4x4 matrix. I know how to determine the eigenvalues, but how do i plot them? Because i saw that plot only works with real numbers. The result is a column vector. 

Hi dears,

How can I detect two equivalent matrices? Is there any Maple command for this?

Also, Is there any command to verify that two matrices have the same Smith normalform?

Sincerely yours

I would like to return local variable y (line 4 in showstat) in the attached dummy procedure (s1) without manually adding any comment inside the procedure s1. This procedure is a simple one and easy to copy paste/or change. When we have a long procedure, it is difficult to do so. I will always know the name of the local variable I want (say, y) and/or line number in showstat

Thanks

PS, I want to get y:=array(1..,2[(1)=x,2=zz])

Dear All

I am trying to use differential operator two times in sucession but I am not getting desired differentiation. Please see content below:

I'm sorry if this sounds like a noob question. I am trying to make a matrix from a table, something like Gauss-Jordan Elimination tutor.

For example

maplet1 := Maplet([BoxCell(Table([A, B], [[1, 2], [3, 4]]), 'as_needed'), Button("OK", Shutdown())]);

How do I turn it to 2x2 matrix?Any help appreciated

Just came across actually a couple of applications but seem to be missing the mapleHDLS.src library .  Does anyone have it?

I don't know if they were just lost or removed.  Google can't find it, so I think unless someone has a copy of it from way back I might be out of luck. 

Does anyone happen to have it?

I am working to minimize an objective function concerning a facility location problem (p-median technique).

Can somebody explain how to formulate the constraint equation that involves  1 or 0?

For instance, the constraint x[i,j]  is an element of {0,1}; namely, x[i,j] = 1 if a point is assigned to a facility located at the point j; 0 otherwise.

Thanks in advance.

I am attempting to minimize an objective function that is related to a p-median problem (facility location). Can somebody please tell me how to impose a constraint that comprises 0 or 1? For instance, I wish to assign the condition, x[i,j] = 0 or 1; in other words, x[i,j] = 1 if the point i is assigned to facilty located at point j; 0 otherwise.

Thanks in advance!

Hi

I'm trying to add a new element to an array to a position that doesn't exist (length+1). According to the Maple help sheet, automatic resizing should take care of this. Instead I'm getting the error 'Error, invalid left hand side in assignment'. I tried this in a new worksheet. This is the entire code

L:=Array():
L:=(1,2,3,4,5):
L:=(6):
L;

When I run this, it kicks that error and only returns 1,2,3,4,5

When I do this to a 2D array it seems to work which has confused me more!

Thanks for your help

Hi!

I'm currently using Maple 17 and I'm trying to programatically export .eps 3D plots using the following code:

plotsetup(eps, plotoutput = `square_of_x`, plotoptions = `color=rgb , portrait, noborder, height=4in,width=4in, shrinkby=0.1`)

The problem that I'm facing is:

1- The z-axis label is outside of my figure (see uploaded figure). This happens even if I try to save the figure in .png and it seems that the 'shrinkby' option its not working properly;

Could you help me solving this?

Thanks!

Hi

I have a set P which is filled with 2D elements e.g.

P:={[1,1],[1,2],[1,3]...}

Later I'm wanting to add a new element e.g. {[1,10]}
At the moment I have

P union {[10, 10]}

If I were to print this I get what I want, but I want to update P.
When I try and do

 P:= P union {[10,10]}

I get an error "Error, illegal use of an object as a name"

What am I doing wrong and how can I solve this? Much appreciated!

I have upload the attachment here. in this problem I want to find the comparison. Please check it and please tell me the correction

Is there some way to delete a task from my Tasks palette

At some point I created "My second palette" is there a way
to delete individual items from this palette and how are tasks
added to a customized palette.

Any help appreciated, Thanks! Les
