Hello all

I have a worksheet where I solve numerically a system of differential equations and define a lot of quantities based on the solution. Since I have to plot alot of stuff and make a lot of fits, the worsheet got cluttered and it's not so easy to find what I want anymore (besides, just running the entire thing takes A LONG time). So my question is, can I save the solution and the quantities I defined and use it as a "kernel" for other worksheets, so I can have...

testeq() gives inconsistent results. See this example:

Equation (1):

hey guys , my concern is about boundaries in random matrix or rtable. so, i can garantee that boundaries in  matrices are in 0 and 10, but i can´t impose a restriction  like the sum of row must be equal 10 for example.
help !! 

pop:=(10-0)*ArrayTools:-RandomArray(proc(A)
local i
if A::rtable[row] then 
seq(A(i),i=1..NumElems(A));
else
args
end if 
end proc(10,3))+0; 

Hello!

Maple 16 differs from Maple 15  (Linux, 64 bit )  in that the plots (both 2D and 3D) have all lines contoured in black.  

How to disable such new behaviour?

Sorry, I understand that my question sounds crazy, but that's what happened:

  I had a working Maple program  and Maple 15 installation on Ubuntu 11.10 64 bit

After I updated to Ubuntu 12.04 ,  Maple 15  starts, but returns almost all (except most primitive)  integrals unevaluated.

My old working worksheets not return all integrals unevaluated. 

Same with Maple 14. 

I have no idea what could have happened...

Hello,

1-I have one calculation and the result is "Error, (in expand/bigprod) object too large"... What can I do with this error?

thamks alot.

Dear Maple users

I have had Maple creating graphics for me that I cannot do in other programs I have access to: 3D pictures of circle waves interferring or even the result of an interference pattern from a diffraction grating in Physics. But when it comes to simple animations, I am not all that impressed.

Basicly I have three complaints: 

a)  Maple seems to use a lot of space to save frame information, resulting in large filesizes.

Hello,

1-I have one calculation and the result is "Length of output exceeds limit of 1000000"... What can I do with this error?

2-I have one calculation and the result is "Error, (in expand/bigprod) object too large"... What can I do with this error?

here is my code i want to run the loop for every value if there is invalid input in lhs(ans(1)) the loop should not stop and check for next value

x -> R T (x ln(x) + (1 - x) ln(1 - x)) + Omega[l] x (1 - x)

hi

thanks for your responding, but i need the analtical solution not numerical . could u solve it again

diff(x₁(t),t)+x₁(t)+0.03x₂(t)+0.01y₁(t)+0.02499y₂(t)+.009y₃(t)=0

diff(x₂(t),t)+0.833x₁(t)+0.69985x₂(t)+0.13745x₃(t)+0.02499y₁(t)+0.06245y₂(t)+.00227159y₃(t)=0

diff(x₃(t),t)+0.109073x

Hey,

I am trying to linearize a Statespace and extract the linear matrices from the solution. Using following example, can you explain how to extract the matrices a,b,c,d.

hi

would u please to help me in solving this system of this equation.

diff(x₁(t),t)+x₁(t)+0.03x₂(t)+0.01y₁(t)+0.02499y₂(t)+.009y₃(t)=0

diff(x₂(t),t)+0.833x₁(t)+0.69985x₂(t)+0.13745x₃(t)+0.02499y₁(t)+0.06245y₂(t)+.00227159y₃(t)=0

diff(x₃(t),t)+0.109073x₂(t)+0.195455x₃(t)+0.00909y

Hello,

I am wrting a program to generate the kaplan york map,

i am suppose to ouotput a sequence of x,y points

I have written my program, but am having a hard time getting the map.

In my program i return x[n],y[n].

After i read my program into  maple, what commands do i use to produce the map?

We are proud to announce you about the new feature in the Maple Programming Environment - Importing existing MPL files into a Maple Project.

You can ​update Maple Programming Environment using Update Manager mechanism in the Eclipse.

The following article briefly introduces the migrating process using the new import wizard,...

Please could you help me answer this, Thanks!
Use a nested for loop (that means two for commands, with one inside the other) to create a list of all pairs [a, b]
 where a and b are positive integers from 1 to 20 and a/b is also an integer.
