I need the plot for the attached problem. I need it before 3 April 2009. Please some one help me.

Thanks

Hi to all,

I am new to maple. I want a maple procedure for the following Boundary values problem.

Thanks

Any one can help me. I need the plot of W(i+1/2)=1/2*(W(i)+W(i+1))+1/2*sqrt(sagma*t)*g(i)    where g(i) is an independent N(0,1) sample.

How do I do this?

Hello,

I need to create a density plot from data in a 50x25 matrix (measurements of Platinum concentrations on the surface of a circular metal disc).  Wich is working fine more or less.  Except I am unable to create a legend wich tells me wich shade of grey corresponds to wich concentration.  Is this possible in maple? I've tried the legend option but to no avail.

Hi experts, I used matrixplot for plotting B[n,m]. In B[n,m] I saved n->17 and m->17 values (so 17*17)...... when I use matrixplot(B,.....) I get the following error message: Error, (in plots/matrixplot) invalid input: `convert/Matrix` expects its 1st argument, M, to be of type {Matrix, Vector, Array, array, list}, but received B thanks a lot for your help!

Hi, i am new to Maple. I am having so much trouble right now...

I need to draw directions of eigenvectors. Can I get some help?

x'(t)=  A * x(t)

A is a 2x2 matrix.  First row 1   1    Second row   4   1

Thank you all.

I need to plot this. Help!!!!! I am stuck.

 

with(linalg):

A := matrix(2,2,[1,1,4,1]);

exp(A*t);

B := exponential (A, t);

c := matrix(2,1,[c1,c2]);

multiply(B,c);

x := t-> first row of the matrix above

y:= t-->second row of the matrix above

I need to plot x and y in this case. What do I do next ???? :(

 

I need to find the first local extremum of a polynomial function. For my purposes I need to start at 0 and go toward increasingly positive values of the independent variable. I also need to be able to specify whether I am looking for a maximum or a minimum.

Is there an easy way I can do this?

Thanks!!

I installed maple 12 as root user successfully. But sometimes simple command like
1+1 or any command takes a long time to complete. After a long delay maple
displays result. It's happening very often and it's annoying. I'm using Debian
Etch, kernel 2.16.8-custom.

Hi there, I am ultimately trying to solve a system of differential equation numerically that reads

diff(y(x),x,x) + (2/x)diff(y(x),x) + y(x)(1-(y(x))^2) = (F(x) - G(x)/x^2)
(1/2 - Xi(x))F(x) = -diff(G(x),x) - (1/x)G(x)
(1/2 + Xi(x))G(x) = diff(F(x),x) - (1/x)F(x)

Hi to everybody. I have to create a fortran output a lot of time for different polinomials.and CodeGeneration gives me an error. i give you a simple example to understand my problem:

restart;

  with(LinearAlgebra):

 with(CodeGeneration):

 np:=10;

 basex := Vector(np):

 for i from 1 to np do

    basex[i] := unapply(x^(i-1)-1,x);

 od:

 Fortran(basex(x),optimize,deducetypes=false,defaulttype=numeric);

Hi

How do I use Maple to create the following Euler circuit

I have already created the circuit now I would like to know how can I create it using Maple.

Hi to everybody. Im trying to use "solve" to find the coefficient that solve a set of equations(a set of polynomials).

I can not manage to figure out how to shade specfic regions under a normal curve. For example:

with(Statistics): X:=RandomVariable(Normal(0,1)): DensityPlot(X, range= -3..3)

I want to shade a region greater than or less than some X value.

Similarly, I would like to add a vertical line for some X value.

 

Thanks,
