So here's my problem: Find a continuous solution to the integral equation: f(x) = (1/2)*[integral_[0,1](x*y/(y+1))*f(y)dy + x^3] by finding a fixed point of the fucntion psi:(C([0,1]),d_inf) --> (C[0,1]),d_inf) psi(f(x)) = (1/2)*[integral_[0,1](x*y/(y+1))*f(y)dy + x^3] . Here, C([0,1]) is the set of all continuous functions over [0,1] and d_inf is the supremum metric. I honestly have no idea how to do this. My professor said this... A fixed point for the map psi is a solution of the integral equation.

 dear all:

   i have wirte a programme for a defined function as follows:

  med := proc (f1, f2, f3) if f3 <= f1 and f2 <= f1 then if f3 <= f2 then f2 else f3 end if elif f3 <= f2 and f1 <= f2 then if f3 <= f1 then f1 else f3 end if elif f1 <= f3 and f2 <= f3 then if f2 <= f1 then f1 else f2 end if end if end proc

#the med function is for get the mediume number from any givend three numbers.#

<p>Hi,</p>
<p>I'm a new Maple user. I'm trying to do something like this:</p>

I am posting it again. 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. Please some one help. i have attached a file of the plot which I need.

How to write expression with customized physical units in maple 12.

For example I want to how write the volume units in microliters.

Thanks

Hello,

I am trying this evalm example (from the help page of evalm, Maple 12):

restart;

alias(Id = `&*`());

# Simplification of matrix operations

evalm((`&*`(`&*`(A, B), 2))*B-`&*`(B, Id));

 

Error, (in evalm/amperstar) &* is reserved for matrix multiplication

A and B are not defined as Matrix in the help page. Is it the problem?

 

 

So given characteristic polynomial of a 2X2 Matrix of char (A,x) = (x-1) how do I find all possibilities for the Jordan and rational canonical forms?

Thank you!

Hi to all

I want to convert a maple file to Latex. How it sholud be done. Any one can help me.

Thanks

Hi Maple experts,

hi, I have 12 equations that I want to solve, when I try to solve them using maple 12 it gives me nothing just empty [ ]  but when I remove an equation from them, maple solved the other 11 equations !!

but i want to solve the 12 equations together.  the equations are :-

exp(-z[1][1]/t[1])*(sum(p[2][j]*exp(-z[2][j]/t[j]), j = 1 .. 3))*(sum(p[3][j]*exp(-z[3][j]/t[j]), j = 1 .. 3)) = t[1](1-w)/(p[1][1]*w),

is it imaginary:

 

evalf((-1)^(1/3))

Dear Experts, I have created the tabel B[n,m] with an high amount of values (n=1000,m=1000). Now I saw that I need a matrix for my further proceeding. But just running the thing again with declaring B as a matrix would take too much time. So my question: Is it possible to convert the table B afterwards into a Matrix B?

I'm trying to plot and need to use implicit plot to graph 3x^2+2xy+y^2=4 on the interval [-5,5].  Any help would be appreciated.

 

How do get the range and domain of an equation for function.  x^2-1/x+1 = 0    or for f(x) = sqrt 144-x^2

 

Hi everyone,

I recently started to use maple and some problem arised that I can't figure out what to do.

My first problem was to multiply 2 Matrixes with GF elements, but I successfully overcame that problem by creating my own procedure to multiply matrixes, so no problem there.
