Also there are 2 examples of "Upper Shift" matrix- 3by3 & 4by4.I need a general index notation for this kind of matrix.(e.g. kronicker delta_i,j represents identity matrices).I tried with kronicker delta_i+1,j;but it doesn't give...


I've some problems in factorising terms in an equation.

As one can see in the maple file below, the terms "cosh((1/2)*a+(1/2)*y)", "cosh((1/2)*a-(1/2)*y)", "sinh((1/2)*a+(1/2)*y)" and "sinh((1/2)*a-(1/2)*y)" recur in the equation. So want to factorise those terms, but it doesn't work with factor().

Does anybody have a solution, how I can simplify that equation?

For a eqation such as y(t)=2*sin(3*t)

I want to solve its fourier series under the different step,

and plot corresponding figure like the picture below

How should i do?

help me please.



I have spent all morning trying to create a surface plot from a set of survey data that I have. The data I have is in the format xi, yi, zi. It is in Excel in columns. I read some previous questions on this topic, but my plot just comes out all jumbled.  Here is what I coded.

As soon as I figure out how to post images, i will post the plot...



I have a polynomial where each element is of the form  L * x1^a * x2^b * X3^c *x4^d. I want to replace X3^c by a sum of other elements , the number of this elements depends on c.


Is this possible? if so how can I do it on maple?


Hope you can help, thanks!

Portfolio Return Variance


I need help in defining and solving Portfolio Return Variance in maple


sigma_p = sum sum x(i)x(j) sigma(i)sigma(j)

where [sum(x(i)r(i) = r(p))]

Please help

I am trying to use Markowitz theory to optimise a portfolio. At the moment I have got

Can someone send me a clear step by step instruction to install Maple 13 for 32 bit Linux?

My OS is Ubuntu 10.04 LTS netbook edition.

I don't want to install it in home folder,instead I want to create a folder(say,MAPLE) in a partition with a lot of space and then install Maple13 inside this folder.

I have a worksheet that contains various pieces of a robot's dynamic and kinematic equations.  I want to perform different design tasks, taking the base model and working off of it.  I'd like to have only 1 model of the robot and not duplicate it across all of my different design worksheets because things change in the robot model as I switch up tooling, find better means of performing a system identification, etc.

Is there any functionality that would allow...

These days I'm learning "maple introductory programming guide". About the command 'anames()',there is an example illustrated in the picture. I know anames(alluser) yields all the user-assigned names,including names containing a leading underscore ('_').

But I don't know why it yields the word "index/fill", can you tell me the meaning...

Dear Maple lovers,

As a classical worksheet user from the past years, now I'd like to be a "modern" Maple user, using the 2D Input in the modern worksheet mode (I will call it mwm from now on). But, alas, I cannot even solve a simple equation!

To describe my situation let me state the following:

1. I use 64 bit Maple 14 Student Edition (single user) under 64 bit Windows 7.
