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
thanks

Hi,
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.

Hi Folks,
Here is a numerical integration program:
http://people.scs.fsu.edu/~burkardt/f_src/quadpack/quadpack.f90
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.
test:=proc(h)
h(1.1);
end;
proc(h) ... end;
It doesn't gives what I want:
test(x^3);
3
x(1.1)
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 .)

Hello all, I am about to write a simulation which is remarkably redundant and suits itself quite well to parallelization on my multi-core, shared memory machine. Also, I am new to OpenMaple. How does OpenMaple behave in parallelized situations? Is it possible to have multiple threads with independent Maple kernels? Could multiple threads coded with OpenMP or the fork command find uncorrupted solutions? Thank you for any help you may offer! -asn

I want to define the operator
L(g):=(phi*D)(g),
which to be understood
L(g)(x):=phi(x)*g'(x),
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?

Hi all,
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[1]>0, a[2]>0, a[3]>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[1] + x[1]*x[2] + x[1]*x[2]*x[3]. How to compute a derivative with respect to x[1],x[2],x[3] ?
diff(f,x[1]) returns 0.
Another question:
I need to evaluate n- multidimensional integral:
int... ( int( int(f,x[1]=0..1) , x[2]=0..1, ..... , x[n]=0..1 ). How shall I write ?

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:

Has anyone tried to export a 3D plot from Maple 10 to TurboCad 10.5 or 11.2?
When I try this, the dxf file is produced, but when I open it in TurboCad, only a blank drawing is produced. Am I missing something?

I'm faced with the problem of trying to plot a graph of the form, for values of b against a.
a^2:= (b^2*c^2) + (a*d^2)/(a-e^2);
Unfortunately, when I try and enter the above, Maple gives an error and tells me when that the equation is recurrsive. If I re-arrange the equation and then try and get an equation with a purely on one side, using the isolate command, Maple cannot isolate a.
The re-arranged equation is of the from
a^2 - a*e + (b^2*c^2*e)/a - d^2 - b^2*c^2 = 0;
Perhaps I have re-arranged the equation incorrectly.

Hi all, I am asking this for my engineering friend.
We've posted on Maple newsgroup and we just heard that here is another place where Maple experts appear, so we posted it again here to seek more advice -- because we have a struggling problem which annoyed us for several days already! Thank you!

Here is what I want to compute:
t22 := Re((1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*exp(.5*a*t)/
(1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*cosh(1/2*(a^2+2*sigma2*(c
+g*(ee+i*v)))^(1/2)*t)+.5*a*sinh(1/2*(a^2+2*sigma2*(c+g*(ee
+i*v)))^(1/2)*t)))^(2*a*xbar/sigma2))
Assuming all variables are real and positive...

Let's say you want to compute
Re(Gamma(a+b*I))
where a and b are real.
Is there a way to obtain a good form of the real part and imaginary
part?
