Hi everybody, 
 
 My goal is to generate the Matlab code of some Maple function f(x, a, b, …).

The command   CodeGeneration[Matlab](f, output=string) first produces the warning

Warning, the following variable name replacements  were made : a -> cg, b -> cg1, …

plus the desired code

freturn :=f(x, cg, cg1, …)
….
end

As you see here the names a, b, … are no longer arguments of f.

I  have searched in the help pages for CodeGeneration (but with no success at all),  a way to force the translation to conserve the original variable names (a, b, …).

First question : Did I missed the information ?
                            (in which case sorry for the inconvenience)
 
Second question : If not, does it exist a way to “catch” the warning and thus keep the replacement rules CodeGeneration does ?

Thanks in advance

 
No need to hurry, esthetics is not a vital issue ... but thanks in advance.

PS : sorry for the syntax errors "waves" generated in the original Word document

Good morning everybody.

I have tried Explore to draw plots in an interactive way.

The function I want to draw (plot3d) is automatically constructed by a specific code, as well as the names of the parameters it depends on. These are of the form P||1, P||2, ...P||N (N is an integer determined during the construction)

... but I did not succeed !

After some investigations I was able to reduced the problem to the following one

N  := 2:
F  := add(P||k * x^k, k=0..N):
G := [seq(P||k=-1.0 .. 1.0, k=0..N)]:
Explore(plot(F, x=0..1), parameters=G)

The result is the classical imbedded window with a plot of -1-x_x^2 and three sliders below.
But as soon as I push anu of them the plot disappears and connot be recoverd.

But the following sequence seems to work as expected

N  := 2:
F  := add(P__k * x^k, k=0..N):
G := [seq(P__k=-1.0 .. 1.0, k=0..N)]:
Explore(plot(F, x=0..1), parameters=G)


Before changing my code, could you please confirm me that parameter names such that P||k are not correctly accounted for by Explore ?


Auxiliary question : more generally, are there points which I have to count carefully when I use the P||k construction ?

Thanks in advance

Good morning everybody


I know this question has already been widely discussed, for example in
http://www.mapleprimes.com/questions/149585-How-To-Order-Legend-Of-Multiple-Plots

I used the answer Kitonum then gave because I have basically the same kind of problem.
As an illustration, here is a sketch of my coding :

N := 3:
for k from 1 to N do
   ...
   MyPlot||k := PLOT(CURVES(....)):
   ...
end do:
plots:-display(seq(MyPlot||k, k=1..N));

The only difference is that I use PLOT instead of plot ... so I have thought that using LEGEND instead of legend would give me the desired result.
But I don't understand how to use LEGEND and how to place the legend in the correct location.

I will appreciate any answer,
Thanks in advance
