I am using CodeGeneration[Fortran] to generate a Fortran subroutine.  The subroutine simply takes a vector state as input and generates a large matrix as output.  However, upon calling "Fortran" I have been getting the following warning that I have not been able to figure out:

"Warning, character limit for Fortran77 statements exceeded; please filter input through codegen[split] first."

If anyone can provide some tips, I would appreciate it.

Hi, I have recently started working with Maple. I need some help with solve command.

Now if I run solve on above two equations for values...

I keep getting this error,

not matter what command. 

How can I solve this please?

Hi,

I have the following function:

y(t) = _C1*exp(-2*t)*sin(6*t)+_C2*exp(-2*t)*cos(6*t)

My start parameters are y(0)=1, and y'(0)=2

How do I isolate _C1 when y(0)=1?

Thanks in advance

Hi 

Hi have made my first package in maple, and need some help. I've got a funktion, and need maple to put something into this function.. 

Dams := proc (a, b, c)

local A, f;

 f(x) := a;

printf("\nDin funktion er %a", f(x));

 A := diff(a, b);

printf("\nDen differentierede funktion er %a", A);

use x = c in f(x);

 printf("\n%a i ligningen ", f(x));  ...

In the name of God

Dear my friends

Hi

 I have a function as the following:

 temp:=phi(Lambda(tau, 0), tau, 0)+((D[1](phi))(Lambda(tau, 0), tau, 0)*(D[2](Lambda))(tau, 0)+(D[3](phi))(Lambda(tau, 0), tau, 0))*q;

 I have equivalent functions for Lambda(tau,0) and phi(Lambda(tau,0),tau,0) as the following:

 c[0](tau) instead of Lambda(tau,0)

y[0](c[0](tau),tau) instead of phi(Lambda(tau,0),tau,0)

1. Still can't figure out how to scale images and text. I tried putting an image in a table cell with some text next to it. The only way I can see is to put any images in a space by themselves and not relate them to text. What I see on the screen has little relevance to the printed product, and the only way I have found to scale images correctly is by trial and error. See #6 below for time penalty for changing a table cell size.

2. I don't get to choose the header/footer font size?

3. The footer date format is 12/1/10, which is very nearly the worst it could be, and doesn't respect my Windows settings: 2010.12.01.

4. There is no option to use the file save date rather than the current date.

5. Dragging a corner of an image changes the scaling. IMO, that's what the tabs on the sides and top/bottom are for. Dragging corners should preserve scaling.

6. Changing a cell size in a table means waiting 10 s to get full access to Maple menus and the document (dual 3.4 GHz CPU, 3 GB RAM).

7. I clicked on the Space Shuttle Sim to get an idea of what Maple can do, and then waited 10-15s while Maple played with the palettes and swapped to a new document.

I guess that Maple is about more than this, but I am [relatively] new to it, so I begin where I can...these are usability issues. I understand that Maple has been selling the doc interface for a few releases, but not made much progress.

I guess that I can kiss (no, I'm not upset, just a style of speech) off the document mode and just use the power of Maple to calculate what I need and copy the results in to a word processing program...

[a few hours later] I should say that I found some more comments on the slow interface, and took the hints to close the palettes, which sped things up quite a bit...the penalty is, of course, that I must open them to use them, and that sort of defeats the purpose. Still, if I regard them as drop menus...

There is still the issue of scaling images, and I guess from a quick glance at the included examples that Maple has not figured out how to handle images. I tried to lock the image size, but have not found a way to do so. The quick tutorial on the Maple web site was a great help in getting up to speed quickly.

Hi, this is what I did and got an error.

Mathematica 8 is out and claiming over 500 new features.

Looking through the list they are mostly things that Maple does not do but probably should. Perhaps for Maple 15?...

How would I go about plotting four individual points in three dimensions, all on the same set of axes?  I'm trying to create a visual of a tetrahedron.  Thank you.

I do not understand why different results are displayed. I would like the solution to be the smallest positive value (ie:4) but cannot seem to do this.

Thank you

Sometimes when I solve an equation using asumming somtings go wrong.

Exampel:  solve( x^2=4,x) asumming x>0 gives me two solutions!What is wrong?

janstef

map(x-->x^2,x+y)   the ruslt is  x^2+y^2,why it's not (x+y)^2 ?

Hi, this is my first time here so hello! So im working on some questions my teacher gave to me in my class, and im having quite difficulty getting started on them, if anyone could help, that be great, thanks!

2. The first application of Newton’s method is to solve the equation

x

Hi,

I have the eq. as shown below:

2*x^3+(2*K1*nbo4+3*K2*nbo4*PH2O)*x^2+3*K1*x*nbo4^2*K2*PH2O-3*K1*nbo4^2*Ti*K2*PH2O = 0

where x is the only variable, however I would like to solve this eq with respect to x for a list of 5 different values for the constant K1 (e.g. 1, 2, 3, 4, 5), and then get an output with the 5 numerical solutions to the eq.

I have tried to make the following matrix:

K1 := [1,2,3,4,5]

fsolve(2*x^3+(2*K1*nbo4+3*K2*nbo4*PH2O...
