Is there a way to find out the rate of decay of function f(x) when x-> +infinity?
I just wanted to use this real-world engineering problem to practice problem-solving using Maple.
Suppose I have a function f(x) (probably complex valued),
how to find out its rate of decay as x approaches +infinity?
I used "limit" but it will give me a value, not a functional form.
I already knew my function has a limit =0 at x=+infinity.
And it is of fast decay.
I would like to bound the limiting behavior of f(x) by exp(-alpha*x) for some suitable constant alpha.
Is there a way to handle this in Maple?
I would like to set up library(s) of routines that can be accessed as part of MapleNet applications. MapleNet applications are prevented from doing file i/o unless you specifically "unprotect" your server.
Is there a way to set up libraries on my web server to safely get around it?
Or is there a way to include my library routines while I'm building my maplet application, without copying and pasting in the source?
I am using Maple since a year and I am used to work in the classic worksheet.
Now I wanted to try out the regular worksheet (you also have document mode). This worksheet is completly different from the classic one. By example I can not find a way to insert text in that worksheet. I click 'text' (F5) then 'Maple Input' is highlighted. I change it to 'text' and type some text. I press enter and ' ";" is missing ' is displayed. This is just text not a Maple command... How can I let this sheet now I only want to insert text?
Thanks in advance,
Is it possible to stop a section in maple 10 classic worksheet expanding on execution? I see from past postings that you cannot lock the section but I just want to keep it closed.
I only want to see the final results on execution and I have to scroll past all the expanded sections all or click on all the sections to close them
I am new to Maple and am having trouble with what should be a simple task. I have a series of simultaneoous equations of the form a*x+b*y=c etc. I have found an initial equilibrium by choosing values of x and y which give me reasonable values of a and b (using the Solve command I have output of a,b,c,x,y which satisfy my equations).
Now, I need to use the parameters I have, my a,b,c, to try and retrieve my x and y (my real aim in this is to see the effect on the x,y when I change the a,b,c). When I try and put the equations plus parameter values into Solve it takes a very long time to solve (I stop after 20mins). What I want to do is use the equilibrium values I obtained before to give Maple a starting point to search for a solution.
Here is a numerical integration program:
In evaluating the integrand functions, it is good to do two function
evaluations at the same time simultaneously.
I just found that I have two CPUs Pentium Xeon 2.4GHz, each supporing
only up to SSE2.
Although the CPUs are slow, but if I can utilize them to do parallel
computing of the numerical integration. It would be great!
But I am not a Fortran expert, nor am I a CS major...
Could anybody give some easy-to-follow advice on how to make that code
parallel on two CPUs?
Documentation on how to reference or assign values to elements in Table is limited. I uploaded a copy of a simple code (690_MTable) which tries to assign values to the elements the table. Code does not give and error message but does not do what I wanted to do.
Please replace this text with the link to your file.

I can plot this fine in Mathcad so I know it should work. But in Maple I am only getting a single point at 0 and another at 10.
plot( (-1)^x, x=0..10,y=-3..3, color=blue, style=point);
Thanks for any help,
I want to write the function into the proc.
proc(h) ... end;
It doesn't gives what I want:
I would like to obtain 1.331 .
More explicitly, how can I write into a proc
a function directly, say x^3?
(Not defining earlier h:=x->x^3 .)
I want to define the operator
which to be understood
phi is a fixed smooth function.
One solution would be to write a procedure, but I
would like a more elegant method.
How can I do it?
I am having lots of trouble using C codegen in generating C code from Maple expressions.
My questions are:
1. How to assume each element of a whole array or vector >0?
Of course I can do:
Assume (a>0, a>0, a>0)...
But I have "m" elements, how can I do that for all m elements?
2. What to do if the output says "the output length exceeds maximum limit of 1000000"?
This occurred when I tried to "simplify" some complicated expression... obviously Maple did get some results, but it refused to print them out due to length limit, ...
3. There is no way to translate the result of "JJ16:=optimize(JJ15, 'tryhard')"?
I have a function of array x[n]: f.e.
f:= x + x*x + x*x*x. How to compute a derivative with respect to x,x,x ?
diff(f,x) returns 0.
I need to evaluate n- multidimensional integral:
int... ( int( int(f,x=0..1) , x=0..1, ..... , x[n]=0..1 ). How shall I write ?
Maple 11 has included indicial notation capability to its new Physics package. This is a good start in performing tensorial calculations using Einsteinian summation convention. However, I wish that Maple further adds the following capabilities to make this package of practical use to folks involved in tensor analysis. This wish list is based upon my personal experience in using tensor analysis for continuum-mechanics and is in no way representative of the community involved in other fields like the theory of relativity.
1) Both covariant and contravariant indices are denoted in subscript. Including the convention of posting counter and covariant indices in super and subscripts, respectively, will help to improve the readability of the printed results.
I have a rather complex statistical problem and was wondering if Maple would be able help.
For my Oxford University thesis I have conducted a survey which seeks to estimate respondents' values for a certain preference parameter (relative risk aversion, RRA). This parameter is continous, but my data is categorical, i.e. the parameter value of each respondent is only estimated as a range. There are eight such categories.
What makes it more complex still, is that the data is censored. The lowest category has no lower limit, and the highest category has no upper limit. The actual categories are as follows:
