Hello everyone!

I'm using Maple 18. The problem is that fsolve does not solve equations, or more precisely, it does not pass the values of sU - from its range, and sV - from its range, to shootNL. As a result, R value:=[]; . I would like to ask for help in solving this problem.

I have attached the Maple source file.

Hello,

I am a beginner using Maple 18. In the procedure I am analyzing, the result is 0.*I. This result means that the procedure cannot be completed until the end, displaying the graph. I am attaching Maple worksheet. Please help me solve this problem.

My equation is

at  x=0

I got g'(0) in my previous equation,

,,

And all the parameters are mensioned in the worksheet.Then how to plot eta.Help me.

Thank you

Hi every one

I need a command or simple procedure to convert an ODE into a linear polynomial.

For example, let us consider the ode in the attached file. I want to return the poly in this file. draft1.mw

Could you please help me?

How to plot this equation

 y(x):=

where,

A := Matrix([[1, -1, 1, -1], [1, 1, -1, -1], [-1, 1, 1, -1], [1, 1, 1, 1]]);

i want to find fitted parameter value for G1,G2,G3,tau1,tau2,tau3 and plot stress-strain curve that fit to true_stress_strain curve(experimental data)
and i tried many times and still get error..can anyone please help me.here is my maple file...

Could you please help me to solve this error.

my code is here.

Please Help.

I have solve this problem in Runge-Kutta Method but i'm getting error.Can you solve this in RK Method or How to give a code for Shooting Method.

Here is my code.

X is a real random matrix of dimension n; its entries are i.i.d. variables.

They follow the standard normal law N(0,1).

I want to write a big sample. For that, I use the following two lines:

roll := RandomVariable(Normal(0, 1))

X := Matrix(n, proc (i, j) options operator, arrow; (Sample(roll))(1)[1] end proc)

Is there a method that does the calculations faster ??

Thanks in advance.
