Hi
first : My English not good,so excuse me.
I have a problem with this:


1)C+Z*(C)*X=D where;

I know D , Z and X are matrix(n*n),(known)
but i can`t find C or Solve (1)finding C(matrix(n*n))

In all versions prior to and including Maple 13 the Histogram default incorrectly displays the data.  Has this been fixed in 14?

eg.

a:=[1,2,3,4,5,6,7,8,9,8,9,7,6,5,4,2,2]

with(Statistics):
Histogram(a,frequencyscale=absolute,binwidth=1)

Clearly the...

I just finished submitting an SCR: the link to spec_eval_rules at the bottom of the ?procedure help page doesn't work in the Online Help (it works in Maple itself, though). And I can't get ?spec_eval_rules to work directly, either, in the Online Help.

Also I was wondering, how about a badge for a certain number of SCRs?

The sample code below generates a message: Error, too many levels of recursion.  It appears to be in the permute function, and seems to be related to variable names I have in my program.  The "error" is intermittent - it appears to work for some but not others eg  aaa:=permute([a,e,i,l,z], mm); does not work but aaa:=permute([e,e,k,n,s], mm); does.  I suspect that it is not liking some variable names in my program.  Any hints or suggestions much appreciated.

How can I animate a plot into another plot?

For example x^2   into  x^3. 
I know this doesn't work but I mean something like this   animate(plot,[x,x=x^2..x^3])

Is it possible to use Maple 14 to solve a system of second order partial differential equations numerically. I have tried to do this and keep getting the following error messages:

Error, (in pdsolve/numeric/plot) unable to compute solution for t>0.: matrix is singular.

Error, index must evaluate to a name when indexing a module.

I am concerned that there may actually be a problem with the system of PDE's I have set up not...

Depending on the number of bars in a histogram.  The bars vary their width. 

Why is it not consistent?

In Maple Help under [worksheet,documenting,table (Tables)] exists one example of Creating a Table of Values. I want to reproduce this example, but without luck. Please can someone show me how to do this?

Here is how it looks in Maple Help:

Hello, I am attempting to import a .pdb file into Maple, as part of converting some Mathematica code to Maple.  I need something that that can accomplish something equivalent to the Import command in Mathematica.  I have tried using readdata, ImportData and fopen with little success.  If anyone has any suggestions, that would be of great help.

The label for the horizontal axis refuses to be printed no mater what I tried. I can insert, change and manipulate the vertical axis label but not the horizontal. I don't know what else to try.

Hello

Very broad query, but I was wondering if anyone has experience of converting Mathcad code to Maple (v13)? I have a series of files that I am looking to re-code in Maple but am having some issues with equivalent syntax etc. The code varies from simple work to more complex studies with variants of FFT (including complex values).

Any help would be most welcome.

Dear Sir

I want to solve system of algebric equations using matrix

can you help me to do that

I guess this is trivial, i just want Maple to apply the convert-to-product-rule:

i typed in sin(x)+sin(x+Pi/3) and looked for some related command in the context menu, but expand,combine or simplify or else didn't work.  What did i miss ?

Hi

I have this sequence which I would like to find an equation f(n) (using RSolve?).

the independant variable is n.

n=4,5,6....inf (incrementing by 1)

f(n)=2,3,3,3,4,5,5,5,6,7,7,7,8,9,9,9,10,11,11,11,12...etc

(an even number followed by three subsequent odds and so forth)

thanks!

I cannot solve this for i. When I use maple I get a big result with a RootOf function that I don't know how to handle. I've looked around and I cannot find anything that will help me.

Can someone please show me how to solve this?

Thanks!
