what are _C1 and _s1?

When I execute several times my maple code the program completely freezes, even though in the beginning of the code teh command "restart" is inserted. I work with matrices, perform integrations and derivations for their components and calculate eigenvalue problems. The freeze happens at no particulat block of execution.

Any thoughts?

except kummer representation, can dsolve output simple? or any other method to do this?

s := x;
tau := alpha - 1 - x;
source := s*Diff(y(x),x$2)+tau*Diff(y(x),x)+n*y(x)=0;
sol := dsolve(source,y(x));
target1 :=ztrans(sol,x,z);

when N = 1
target2 := sqrt(1-a^2)/(1-a/z)*((1/z-a)/(1-a/z))^(N-1);

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.

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

Thanks alot.

When I use ImportMatrix to import a MATLAB mat file, I get a list of names and values. Should I write a "for" loop to assign them in Maple or there is an easier way to do it?

I am working over F_p, where p is prime. When p = 2, the number of 2x2x2 arrays (aka hypermatrices or tensors) over this field is 2^(2*2*2) = 256. Of those 256 arrays, I only want the symmetric ones: that is, if x_{ijk} is the ijk-th element of the array X, then x_{ijk} = x_{ikj} = x_{jik} = x_{jki} = x_{kij} = x_{kji}. Is there a quick loop that does this? 

how to solve this partial differential equation  :

d/dx[(1+e*T)dT/dx]+P*dT/dx-B*T=0

e ,p ,b are constants and t is temperature.

plz help in finding a solution for this differential...or the closest method to simplifying it...

Question 1. After googled, x*diff(F,t)+t*diff(F,x) for two variables, how about three variables or general ?

Question 2.

if deal with on variables case using the example in

http://demonstrations.wolfram.com/AFunctionInvariantUnderAGroupOfTransformations/

F := (x^2-x+1)^3/((x^2)*(x-1)^2)-y;
G:=y*diff(F,x)=0;
sol:=solve(G,y);

F(H)-F = 0
sol:=solve(F,x);
H := simplify(subs(y=F, sol[1]));

all above code can...

Hi,

I need to get inverse kinematics model of a double inverted pendulum. I got a model but it gives error when I run. It seems to me that the inverse kinematics model is not quite right. If you are able to help me, I will be very pleased.DoublePendulumI.msim 

Thanks for your help....

I would appreciate a hint why Maple 16 Classic under Win XP 32 bit crashes due to the following sequence of commands

> dir1:="C:\\Maple16\\P16\\test1\\";
> path:=cat("dir ",dir1);
> ssystem(path);

with the lasst ssystem command doing the crashing while the same sequence of commands under Maple 13 Classic does not: Instead, system returns to Maple 13 worksheet the content of the directory "dir1" as expected.

Is there another way to issue that ssystem command?

hello,

after defining N_1 N_2 and N_3 with long numbers, and defining M by N_1*N_2*N_3 i tried to step backwards.

By entering something like: M/N_1 (what is exactly like N_2*N_3) it does not show me full numbers, but instead 1/something*M.

After refreshing M and afterwards refreshing M/N_1 it totally worked out and showed me the product of N_2*N_3

Now my question is: how can i prevent this odd display format without refreshing everytime? (i tried...

Hello,

I have to design a wheeled mobile robot for my bachelor-thesis. the robot should be controlled in Simulink. Therefore, I have to use the Simulink Component Block Generator. Outputs are: yaw angle/rate, absolute position in x/z and its derivatives, wheel angle and its derivative,steering angle. Inputs are one torque for steering and one torque for actuatuating for each wheel. -->6 torques (3 wheels). When I click on the "Generate and Compile...
