hi all

 

i have tow equations and i want plot q vs.A , that A change beetwin 0..phi. vn and a are definite and positive.

plz plz help me

 

(diff(f,y))^2-(f[y]^4)/4+q^2/(f[y]^2)+(1+2*q^2)*(f[y]^2)/2=piecewise(y<-a,1/4+2*q^2,-a<y<a,vn*(f[y]^2)-vn+1/4+2*q^2,y>a,1/4+2*q^2);

phiB[infinity]=q*int(f,y=-infinity..infinity):
A:=phiB[infinity]:

Hi

I have this attched procedure "Alt_lisse1".

Why the result e1 does'nt take into account the known variables

Thanks

ALt_lisse1.mw

Hi

is it possible to remove this warning and not to show it when executing a procedure ? 

Warning, `AzIII` is implicitly declared local to procedure `lisse`

Thanks

I have a question about using embedded component in Maple 2015.

I want to import the MapleSim model to Maple and use the "Combo Box" (which is one of the embedded component in Maple) to load the parameters that were used in the MapleSim model.

 

Embedded Component

 

The picture above shows the Maple worksheet that I made simply.

As you can see, I imported the MapleSim file (which contains three parameters, m, c, and k) to the Maple by using "MapleSim Component (Embedded Component)".

After that, I wanted to load these three parameters to the "Combo Box" automatically like the picture above, but I couldn't do that.

(In the case above, I manually type m, c, and k in the "Combo Box")

 

Isn't there any way to load the parameters to "Combo Box" automatically?

I attached the MapleSim file that I made. It also contains the Maple worksheet.  

[TS]EmbeddedComponents.msim 

 

I appreciate any idea you may have.

Hi, I have 2 Questions about programming in maple. I will be thankful if you help me as soon as possible.

First; How can I display a n*n HilbertMatrix?

Second: I wanna make a 2*2 matrix which its transpose is egual to its inverse, How can I do that by helping reflectionmatrix?

(I'm an amateur programmer, I use maple 13 on my pc)

Is there a built-in Maple function to convert decmial inches to inch fraction. For example 1.74 as 1+3/4 ?

Trival to do in Delphi or c++ or even create a Maple function. However I would rather use a built-in function.

Thanks

I have a pair of linear functions I want to differentiate wrt time. The first line defines the functions, and thesecond a substitution that tells maple that the variables of these linear functions, are themselves functions of time.

F := Vector([p[1]*p[6]*(p[2]-x[1]-x[2])-p[3]*x[1], p[4]*p[6]*(p[2]-x[1]-x[2])-p[5]*x[2]])
timefull := [x[1] = x[1](t), x[2] = x[2](t)]

This line should give the ith derivative

Fdiffi := [diff(subs(timefull, F[1]), t$i), diff(subs(timefull, F[2]), t$i)]

however maple gives me a responce in terms of the pochammer function. Why is this? How do i avoid it?

I am working on a problem that involves a great deal of combinatorics, and I have broken the problem into several procedures.  I am trying to create a first procedure that creates a list output, a second procedure which takes the list and other input and cycles over combinations of two elements from the list and calls a third procedure to perform the calculus needed for each pair.  A simplified example follows:

f1:=proc(a1, a2, ..., an)
(various if-then statements)

return [b1, b2,...,bn];

end:

 

f2:=proc(alpha, beta,...,L::list)

A:=0;
for i from 1 to n-1 do
     for j from i+1 to n do
     A:= A+ f2(alpha, beta, ..., L[i], L[j])
     end do;
end do;

return A;

end:

 

f3:=proc(alpha, beta, ..., bi, bj)

(various mathematical manipulations)
return x;

end:

 

When I first use f1 to get [b1, b2, ..., bn] and then invoke f2 as f2(alpha, beta, ..., [b1, b2, ..., bn]) everything works fine.

However, f1 needs to be invoked by yet a larger function as follows:
...

L0:=[0,0,0,...,0]:
L0:=f1(a1, a2, ..., an):
B:=f2(alpha, beta,...,L0):

...
When I do this, L0 still gets assigned the correct value according the program trace, yet it fails to invoke f3 correctly.  What could the problem be?

Dear friends,

 

I have a huge differential equation which I am trying to solve.

However, even solving it numerically, maple keeps evaluating it for a long time and then stops working! So there is no solution.

I just want to check if there is any solution to this differential equation at all!

Do you know a way with which maple can check if the differential equation is solvable?

 

I need export a r-matrix 300x300 and i received this:

 

Error, (in ExcelTools:-Export) Export failed. Verify that the exported table does not contain more than 255 columns and 65535 rows.

 

How can I export this matrix?
