Hye,

Have a good day Sir.

can u help me how to solve my problem using the Implicit Crank Nicolson Finite different Method. I have attached the problem and what I have done in Word file. I have to modify my Equations in order to get the graphs (that is wrong actually). Can you help how to get the graphs by not change the sign of my equations?:( 

 

Thank you in advance.

God Bless you.

 

 

Aslam-u-Alikum. Hope you will be fine. I have some error in the last command of the attached file. I want this type of answer

 

StressesMultiplication := Matrix(2, 2, {(1, 1) = 7, (1, 2) = 10, (2, 1) = 15, (2, 2) = 22})

How do you move plot labels individually? Just click-hold-and-drag does not work.

How do you color the orbits individually?

Hi,

I am trying to interpolate a set of arbitrary numbers including real ones like Pi and plot them using ArrayInterpolate. This does not work. Is there a simple way around this?

Thank you.

I am trying to find the root of an equation that involves a procedure and a definite integral (solved numerically). Of course, I don't need the root to be found symbolically, but numerically would be fine. The problem is, I keep getting the error

"Error, (in fsolve) Can't handle expressions with typed procedures"

whenever I try to solve it. Anyone have any ideas? My worksheet is here: Table-1-duplication-mapleprimes.mw 

 

I'm computing a matrix which is a hessian of a quadratic function and it should be symmetric.

Unfortunately, because of the numerical errors, the hessian matrix becomes unsymmetric. 

Then, I want to use this matrix as the input for the QPSolve procedure, and I get the error that the matrix is unsymmetric.  

To obtain the symmetric matrix, I'm doing the following redundant computation:

A := MTM[triu](B, 1) + Transpose(MTM[triu](B)):

Is there a better solution to this problem?

AoA. Hope you will be fine. I want to factorize 2046 as

2046=2*1023

but maple gives

ifactor(2046)=11*(2*3)*31

i want to plot a arc that starting angle and finishing angle are variable

but it didn't show the arc there is my code

Hi there,

I used the implicitplot command to plot an implicit equation as follows:

with(plots):

implicitplot(x^3+y^3-3xy=0,x=-3..3,y=-3..3, scaling=constrained)

but maple13 takes error and specifies {xy} as an extra unknown.

Your help will be appreciated.

Regards

AoA. How are you hope you will be fine. Sir the following matrix have been given

A := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = -1, (2, 2) = 2});

B := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 0, (2, 1) = -2, (2, 2) = 3});

C := Matrix(2, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = 0, (2, 2) = 0});

I want to write M by M matrix using the above matrices like this

P:=[[[A,B,B,...,B],[C,A,B,...,B],[C,C,A,...,B],[.,.,.,...,B],[C,C,C,...,A]]]

AoA... I want to plot the following functions

f(x)=sin(x)

g(x)=sin(x)-x+x^2

h(x)=cos(x)-sin(x)

I(x)=exp(x)-x

J(x)=sin(x)+exp(x)

in one coordinate having the line style and legend like attached file.

AoA. How are you? I want to solve the following equation in one step and convenient way please help

 

psi(x):=Matrix(1,3,[x,x-1,x^(2)-x-1])

P := Matrix(3, 3, [1, 2, 1, 0, 1, 1, -1, 2, 3])

U := Matrix(3, 3, [a[1, 1], a[1, 2], a[1, 3], a[2, 1], a[2, 2], a[2, 3], a[3, 1], a[3, 2], a[3, 3]])

u := psi(x)^T*(P^2)^T*U*P^2*psi(t)-t*psi(x)^T*(P^2)^T*U*P^2*psi(1)-x*psi(1)^T*(P^2)^T*U*P^2*psi(t)+t*x*psi(1)^T*(P^2)^T*U*P^2*psi(1)

 

If you reduce my computational work or have any suggestion to solve please give.

AoA. How are you? Hope you will be fine. I want write the following in Loop for any M

 

F[r,s]:=2^(k+2) m sqrt((c[r-1])/(c[s-1])) for r=2...(M+1), s=1..r-1 and (r+s)=odd;

F[r,s]:=0  otherwise
