I've recently updated to Maple 12 (on Mac OS X.4.11) and am still learning how to use it. A search on Maple FAQs didn't turn up any answers to the following questions.

I can find the Smith Normal and Jordan Canonical form of square matrices but as part of our assignment, we have to find the Smith Normal form, Jordan Canonical, and Rational Canonical of a 7 by 8 matrix (all whole numbers). Is it possible to do this with Maple? I only get error messages... Thanks!

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>

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, 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.
