Re: [Scilab-users] compilation with OCaml 4.06

[Florian Blachère]

Hello Clément,

Thanks for the answer, I installed num and changed the compilation line 
to use ocamlfind but now the compilation fails with :


ocamlfind ocamlopt -package num -I ./src/modelica_compiler -I 
./src/xml2modelica -c src/modelica_compiler/optimization.ml

File "src/modelica_compiler/optimization.ml", line 166, characters 21-22:
Error: This expression has type string but an expression was expected of 
type

 bytes

Is it link to the uodate to OCaml 4.06 ?

Hello Florian,

The easier would be to depend on the external Num library for the 6.0.x family 
as far as this
library remains available; statically build against it is the way to go for 
OCaml code. Num might
also be packaged in your system, use ocamlfind to look for it.

Thanks,

Hello,

Scilab 6.0.0 and 6.0.1 (and the master branch) cannot be build using
OCaml 4.06 because this release remove the Num library
(https://ocaml.org/releases/4.06.html#Changes   ,
https://github.com/ocaml/ocaml/pull/1178), do you have any advice to
build Scilab with recent OCaml: integrate Num in Scilab, build Num
oustside of Scilab and link against it, ... ?

Thanks by advance,

Florian

Re: [Scilab-users] compilation with OCaml 4.06

Hello Florian,

Please find attached a patch that fix this issue; it comes from a OCaml 4.0.4 
change which
distinguish String and Bytes implementations and the unsafe-string flag.

Quoting the documentation [1]:
> OCaml strings used to be modifiable in place, for instance via the String.set 
> and String.blit
> functions described below. This usage is deprecated and only possible when 
> the compiler is put 
> in "unsafe-string" mode by giving the -unsafe-string command-line option

[Scilab-users] "intg" and i"ntegrate"

[fujimoto2005]

I want to integrate a user function f(x,y1,y2) from a to b with respect to x.

1, I don't see the difference between "integrate" and "intg". I saw help
file and find "integrate" can manage multi upper limits.  Except it, I can't
find any differences between two functions. Is there a difference in the
accuracy or calculation method?
 "intg" has a fixed number of partitions. Does "integrate" increase the
number of partitions automatically until the accuracy is not improved? I do
not understand the difference with the help file.
2, I could use "intg" with "intg (a, b, list (f, y1, y2))", but I could't
use "integrate" with "integrate (list ("f", y1, y2), "x", a, b)" or
"integrate (list (f, y1, y2), "x", a, b)". What is wrong with the syntax?

Best regards

Hi Offer Pade

Please see : https://atoms.scilab.org/categories/image_Processing

I hope you find here what you need.

[Scilab-users] SCILAB ODE solvers: bookes or notes about it.

[Hermes]

Hello colleagues,
I would like to know if there is a more recent version of the document:
*Ordinary Differential Equations with Scilab
WATS Lectures
Provisional notes
Universit'e de Saint-Louis
2004
G. Sallet *
Or if I can find the scripts of the examples developed in the document.
In the reading that I do of the document I have been developing these
examples. In some cases I get the expected results and in others I do not.

Is there any other similar document !?

Gracias
