If we have a matrix with n rows and 1 column of n-variable function  how to use the subs?

How to implement in maple, the differentiation matrix of second order ?
Is it possible to implement it with the command LinearAlgebra[BandMatrix]?

I can not get the matrix:



Lets look at an example using the following set of 8 discrete points (x,y)

(2,5),(4,15),(6,35),(8,65),(10,100),(12,145),(14,195), and (16,255).

Hi,

I need to extract the extremes of a cyclical function, actually I have all the data (x,y) and I was wondering whether extracting these extremes as I have shown in the attached figure will be easy with Maple or not? NOTICE that the attached figure is actually 2 series of data overlaid, you just consider the blue one and ignore the red one

TIA

Hi,

I wanted to know if it possible to get maple to skip all operations to the bottom if it receives an error anyway through my program? I have a number of seperate lines and don't want to put it into one big if statement.

Thanks

So, i'm using Maple 13 in my school, and our homework was to make two procedures which could calculate something.

I'm interested in making a procedure which can calculate out the angles of my triangle with the law of cosines, and this is how my procedure looks so far:

findA := proc (a, b, c)

local solA;

solA := arccos((b^2+c^2-a^2)/(2*b+2*c));

return evalf(solA);

end proc

findA(67, 50, 34)

After many calculations tried to run eval(exp). Was  in shock :( Big table used. Is there smth like forget(all) to forget all functions. After forget(exp) memory of course lowers enought.

Hello..

I need to write a function in maple which creates matrices from 1x1 to 20x20.. And the filling in the matrix needs to be 1 in the diagonal. But not like the diagonal in the identity matrix, but the opposite..: see picture:

So the amounts of 1 increase depending on the size of the matrix...

I know that i can put the function in a for loop to do the steps 20 times...

Can anybody spot the problem in the second solve() in the attached file?  I am using the same approach that I did for the first solve(), but Maple is returning any empty list. 

Thanks!

I've set up part of my procedure to calculate the values of i from 1 to 15 using for loops.  I only need the values from 1 to 15, but a later part of my procedure if failing because it says it cannot evaluate the value for i=16.  How do I tell Maple that i>=16 doesn't matter/do nothing for i>= 16?

Is it possible to display on a same graph the error of type I and type II error given n, alpha and beta?

Hey,

I've got a nondifferentiable bounded multivariable function and I'd like to find a good approxiation of it's minumum and maximum.
Basicly, I'd like to automaticly be able to return the maximum and minimum of the height of the 3D-plot i have. That would just be perfect.
However, I can't find anything that does anything like this.....

 It is the mathematica code for bifurcation diagram of the model that i am working with now. is there anybody who can translate it into maple code? or does anyone can help me with making a bifurcation diagram for such a ODE system in maple??

Thanks in advance

Noticed that after simplify memory remains in some internal caches. How to free it after simplification done?

Could i manually reset status bar (i.e. memory and time values)? restart; doesn't help.

I was wondering if anyone knew of a procedure or patch for Newton's method with two variables. I checked maple help and there only seemed to be Newton's method for one variable.

It's for root finding when you have two functions, each with one or two variables; it involves a jacobian matrix.

I'm running Maple 13 btw.
