which iterative method does maple use in fsolve command to solve nonlinear slgebraic systems?

When I type
                    printf(cat("Answer: ", sqrt(4)));

The result is Answer: 2. So, everything is OK.

However, if I type
                            printf(cat("Answer: ", sqrt(5)));

I got an error message: (in fprintf) format string expected....

So, I have a list of vectors v1,...v8 - and I want to consider all {0,1}v1 + {0,1}v2+ ... + {0,1}v8 (I need a list of all 2^8 possible combinations). 

I can run 8 simple for loops and use the mod command, but that's inconvenient. Is there a nice way to do what I'm trying to get done? 

Hi,

The model that i uploaded (EqQui.msim) has a component with severall output and 4 inputs, but 2 of the inputs (LgKph2o and Lgkpco2) depends on one of the outputs. The 2 interpolation tables transfor the output variable (temperature) in this two inputs. All components works fine independtly (first "model", the one on the top), but if i link the exit of both interpolation tables mapleSim say it cant solve a lot of variables.

Hello everyone,

I am coding the assumed modes method for vibration analysis on maple and I don't know why but the code takes veeery long time to execute and give results and I think it should not. There is also anoter very annoying thing. every 3 or 4 executions maple freezes completely and I am not able to find the cause...

I would be gratefull if someone could explain me if in my case it's better to working in floating point or rational values,...

Here is my code, I know I am just missing something in the Export (last line) command to make it write the next iteration to a new cell, but nothing I am trying has worked. 

restart:
with(LinearAlgebra):with(plots):with(ExcelTools):

for N from 25 by 5 to 50 do
for b from 0.01 by 0.01 to 0.25 do
for h from 0.02 by 0.02 to 0.2 do
for h1 from 0.015 by 0.005 to 0.1 do
  A1:=proc(N::posint,b1,e1,h0,h11,h21) local M;
      M:=Matrix(N,(i,j...

Hello,

I have created a for loop in which I call often the same function let's say w(x).

Is it processed faster if I call each time the function, or if I apply the function to another variable, let's say W and call W each time?

Thanks

Gamma := sqrt(1-a^2)/(1-a/z)*((1/z-a)/(1-a/z))^(N-1);
int(subs(z=exp(j*w),Gamma)*Conjugate(subs(z=exp(j*w),Gamma)),w=-Pi..Pi)

would like to prove this integration = 2*Pi, however got error

int(subs(z=exp(j*w),Gamma)*subs(z=exp(-j*w),Gamma),w=-Pi..Pi) also not equal to 2*Pi

I need program of multiple shooting method with maple or algorithm?

Thanks alot.

The pyramid is the standard simplex in 3D with vertices (0,0,0),(1,0,0),(0,1,0) and (0,0,1). Ie it's the convex hull of these 4 points. Because Maple does not have "convexhull" plot command for 3D objects, so instead one has to plot a pyramid.

My commands:

                            with(plots);

Hi i have difficulty to obtain the function of theta(eta) and diff(theta,eta) form the matrix. Every time i have to take the values from the matrix inorder to make the function of theta(eta) and diff(theta(eta),eta) which is very difficult.

Can you please make a code in MAPLE so that i may get the direct fuction of theta(eta) and diff(theta(eta),eta)from the matrix gernerated by MAPLE.

i WILL WAIT FOR YOUR QUICK RESPONSE.

Hello everyone,

  I have a file, e.g.'helloworld.txt'. It cotains

hello 3 5 7
world 1 2 6

 If I use

  L1:=readdata(`D:\helloworld.txt`,3):
print(L1);

 I just got a "[]"

How can I get the data from the file which has many word?

Thank you very much in advance

Dear Maple users,

Now I am using Maple-13 in my lappie with Windows-7 (64 bit).

I came to know that there is a special package to manipulate the q-series called as MAPLE q-series package.

Now I wish to have that package for my research work.

I request you to provide me with the complete details about that package. 

 Hi: I access my school's network remotely for Maple14. When I use with(DirectSearch); I get the following message:

Error, invalid input: with expects its 1st argument, pname, to be of type {`module`, package}, but received DirectSearch

I need help and look forward to a solution to this.

Hi guys, my Maple version is 15.01, when I want to do the following plots, the Maple pops up this failure "Kernal Connenction Lost":

Here're the corresponding input commands:

J := u -> evalf(Int(1/(sqrt(x^2+u^2)*(exp(sqrt(x^2+u^2))+1)), x = 0 .. infinity));

plot(exp(-2*J(Delta/(.4))), Delta = 0 .. 1);

Does anyone encouter the same problem if you try the commands? I wonder how to fix it, thank you.
