Is there programs or algorithm to obtain resultant of multivariant polynomials for more than 2 polynomials

Please help me to check this procedure for solving complex DAE, I want to plot this error figures

There are some errors for the initial conditions?

restart;with(plots);w := 10;L :=0.001;R :=1; u(t) :=exp(I*w*t) + 2* exp(I * 2 * w * t);daesys:={diff(I3(t),t) = 1/L*u(t), I1(t) = I3(t) + 1/R * u(t), I1(0)=0, I3(0)=0};dsys1:= map(eq -> (evalc(Re(eq)), evalc(Im(eq))), eval(daesys, {x(t) = xre(t) + I*xim(t), y(t) = yre(t) + I*yim(t)}));

Hi everyone,

I am importing an .m file from MATLAB to Maple using the command: FromMFile(). The .m file uses a set of huge symbolic matrices with an output of a huge symbolic vector of 36 by 1. Each element of this vecot is supposed to form a second-order differential /or algebraic equation that I am planning to solve using the Maple DAE toolbox.

The problem I have is that while I execute the worksheet, Maple only evaluates the...

How does one go about defining a road surface that can be used with the tire library for doing road holding on hills and side slopes?

I need to use Krylov functions widely in my project. They are recurrent functions as follows:

Can I make Maple operate with these functions?

Thanks.

Hello,

it's my first utilisation of MAPLE, and I want to determine the max of a function y(x). I have this differentiel equation with 2 variables :

a*diff(y(x),x,x) + b*(diff(y(x),x)-diff(z(x),x)) + c*diff(y(x),x) + d*y(x) + e*(y(x)-z(x))= 0;

I resolve it whith the function "dsolve", and now and I want to calculat the max of the function y(x).

can any body help me ??!!!

thanks

I worked a problem in my textbook using maple.I define two differential equations sys1:=[dy/dt=...,dx/dt=...] and its linearize point lin_point:=[...],then using linearize command,I obtained a state space description of the system.Now,I want to using state space description to get transfer function of the system,how can I do it directly without retype the state matrices a,b,c,and d manually?

Thank you!

Hi,

I have downloaded the lead acid battery model from the link http://www.maplesoft.com/applications/view.aspx?SID=34125. I have made the whole system as a subsystem block and tried to generate a simulink sfunction block, but I was not successful. I am getting the below error while doing so.

Jacques' post on the maple.vim project spurred this post. Vim users cannot have all the fun.

About a year ago I wrote an Emacs front-end for the Maple debugger. I've used it since---it is now my primary debugging tool for Maple code. What it does is allow stepping through interpreted Maple code in an Emacs buffer. That is, rather than being presented with a single line of...

I am trying to create a Simulink component block from a MapleSim subsystem. I have one input to the subsystem, and the Specified Inputs and Outputs section of the MapleSim Connector worksheet also shows that the subsystem has one input. However, When I export the model to Simulink, there is no input port, just one output. How can I fix this?

Sorry but my question os more for mathematica users: The DSolve result is not correct. What can I do?

Thanks for your advice.

Hi Maple users,

I have a license for the Global Optimization Toolbox (GOT) 12 (i.e. for Maple 12). However, it seems it cannot be installed under Maple 13. As the GOT is essentially a frontend for an external library, I find this restriction a bit artificial and annoying. I don't see a reason why I should buy a new license for something that is practically the same that I already bought...!? Do I overlook something? Is there a simple way of installing the GOT 12 under Maple 13? Thanks for any hint!

So I followed the exact example as in the Maple help for "Matlab[evalM]" which is reproduced below (with my result, which is nearly identical to that in the help example)
