hi

if I have two partition Pi and Pi 'I want to know the decomposition of Pi'

I want to solve numerically the nonlinear problem

a*(diff(y(x), x, x))+2*(diff(y(x), x))+exp(y(x)) = 0, y(0) = 0, y(1) = 0

by defining my own method defined as

y_{n+1}=y_{n}+2*h*(-2*y_{n}+2*ln(2/(1+x))-(1/2)*a)^2/(a*(-4*y_{n}+4*ln(2/(1+x))-a-h*(4*y_{n}-4*ln(2/(1+x))+a+x+1)/a))

where h is the step-size. Please help me by letting me know how can I do this using Maple 11.

how can I caculate the Clifford Algebra in using symbolic expression?

Hi,

The error showed up whenever I tried to do the Maximum Likelihood Estimation with Global Optimization Toolbox.My objective (likelihood ) function f is defined as follows(A1 to A5 are intermediate variables; parameters are x[1] to x[12]）:

f := 0;

for j from 1 by 1 to 21 do

A1 := exp(x[1]+x[2]*c[j]);

A2 := exp(x[3]+x[4]*c[j]);

Solve the equation (x-2)^{(25-x^2)}=1

Let function f(x)=x(2011+√(2013-x^{2})).Find maximum and minimum value of function f(x)?

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!

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...
