What are all the maths that are on this program?

Hi, I have quite a long worksheet. When i press enter one by one, the calculation comes out alright. But when I press the "!!!" sign which means execute entire worksheet, not all the equations run properly, is this a problem in Maple15 or am I using the command wrongly? Please advice. Thanks.

I am using maple 14, and am trying to solve the time derivative of the funtion below

X[3]=L1costheta1+L2cos(theta1+theta2)+L3cos(theta1+theta2+theta3)

wrt theta

seriestoratpoly(series(simplify(LaguerreL(5, x)),x,6),['egf']);

seriestoratpoly(series(simplify(LaguerreL(5, a, x)),x,6),['egf']);

inverse z transform of sqrt(1-a^2)/(1-a/z)

restart;
alpha := 0;
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),method=laplace);
zsol := ztrans(sol,x,z);
convert(zsol, ratpoly);

sol := y(x) = _C1*invlaplace((_s1-1)^n*_s1^(-1-n), _s1, x)
zsol := ztrans(y(x), x, z) = _C1*invlaplace((_s1-1)^n*_s1^(-1-n)*z/(z-1), _s1, x)
Error, (in convert/ratpoly) expecting a Laurent series or a Chebyshev series

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....
