Today I installed Scilab 5.4.0 into a new workstation.
OS: Windows 7 Pro x64
When I tried to run old code from my old machine I got this message
{
!--error 999
Impossible to load parallel.dll library: The specified module could not be
found.
}
even if I tried to run
Dear all,
This a stupid question, but how can I solve directly in, Scilab an equation
such as :
0.403*X^(-0.121) + 60.5*X^(-0.73) - 0.1839 = 0
?
Is-it necessary to code a function ? from memory : dichotomy method, secant
method, Brent one etc. .
Regards
Paul
Hi,
This is a nonlinear equation, for which we are searching a zero.
The fsolve function is designed for this purpose:
http://help.scilab.org/fsolve
Notice that there might not be a solution. This is why the algorithm is
an optimization problem, where the square norm of f(x) is minimized.
All,
Thanks for the feedback ...
... a basic plot shows the curve is monotonic (see attachment) ; I should plot
a 3D curve in order to study the influence of the exponents for example to
verify there's one and only one root ...
... I've to code a fast function to solve this kind of equation
