[Scilab-users] The numderivative function

[Paul Bignier]

Hello Hermes,


If you're using Scilab 6.0.0 the function numderivative is in the differential_equations module so you should use:

  exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);


If you want your script to be compatible with both versions you can add:

  v = getversion("scilab");

  if v(1)<6 then

    exec(SCI+"\modules\optimization\macros\numderivative.sci", -1);

  else

    exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);

  end


Best regards,

Paul

Hi,
When I execute the command:
exec(SCI+"/modules/optimization/macros/numderivative.sci",-1);

I get the following Scilab alert:

exec('C:\Draghilev''sMethod_4.sce', -1)
at line    14 of executed file C:\Draghilev'sMethod_4.sce
at line   -15 of executed file C:\Draghilev'sMethod_4C.sce

exec: Cannot open file
C:\PROGRA~1\SCILAB~1.0\modules\optimization\macros\numderivative.sci.

the command is inserted in the script before calling the fumciont ode.
it is right?
Gracias
