Hello,

This method works in 2d... but in 3d I get a HFloat undefined output when I try and substitute the actual values in to the function. If anyone could have look through the programming and see why this is, it would be really helpful!

Thanks,

I've downloaded and installed Maple, but I can't activate it. Whevener I try and activate it from within the program, it freezes, and when I click Activate Maple on the Start screen nothing happens. I tried the offline activation service, copied the licence.dat file into the Maple license folder, but when I tried to open Maple it still said license file missing or invalid.

I'm using a license provided by my university, and I'm running Windows 8.

1. I use your previous reply on V_G derive  on other characteristic function, but most are undefined

or complicated solution or can not evaluate, why?

for example

charc := 1+i*X/(i*X-1);
int(exp(-I*X*u)*charc, X = -infinity .. infinity);

it got this complicated thing
piecewise(Im(1/i) = 0, undefined, int(exp(-I*X*u)*(1+i*X/(i*X-1)), X = -infinity .. infinity, method = _UNEVAL))

Density := int(exp(-I*X*u)*charc, X = -infinity .. infinity);

Hi, sometimes when i multiply matrix, some of the values turn out to be "Float(undefined)". How do I set all of these "Float(undefined)" to the value zero? Please help. Thanks

Hello.  The ‘optimization’ flag for the fortran codegen or CodeGeneration only will operate on a single array.   It would be very very helpful to me if I could put multiple arrays (all of them having common variables) as input that the codgen and CodeGeneration can automate all at once (im mostly interested in the fortran and matlab codes).  What I do now as a work around is manually put all the multiple arrays into one giant array, then run code...

My Maple plots contain strings like this one:

[HFloat(undefined),HFloat(undefined),HFloat(undefined)]

Let's call them "offending strings" or "errors", as they would most likely have been avoided by more experienced users. These errors arise while creating odeplots. I suspect that these errors are produced by the option Events of dsolve each time a halt is triggered. This is mere speculation and besides the point of my post anyhow.

Maple seems to understand...

b) Define a procedure f(x, y) which returns −1 if x < y and 1 if

Hey guys,

I have the function f(x) =(sin(x) + 1)/(x^2 + 1) where x =-Pi/2 and 3Pi/2

1) I first set up an intgral for the function:
