Hello,
You may have noticed that in the new release of Scilab the help command disappeared in favor of doc. In fact Scilab users have been warned about help deprecation during the last 6 month and should have started to use the new command. However, if you are (as I am) a long-time user of Scilab you often still type help instead of doc and find annoying the error message. Of course this will be fixed in the next minor version (2026.1.0) but in the meantime, I decided to release a module
implementing a pure text help command displaying only the Syntax and
Arguments sections (and advising the user to use doc if further information is needed). Of course, the lifetime of this module shouldn’t exceed 6 month… Just type
atomsSystemUpdate
atomsInstall texthelp
Here is the output of help ode:
--> help ode
ode: ordinary differential equation solver
Syntax:
y = ode(y0, t0, t, f)
[y, w, iw] = ode([type,] y0, t0, t [,rtol [,atol]], f [,jac] [,w, iw])
[y, rd, w, iw] = ode("root", y0, t0, t [,rtol [,atol]], f [,jac], ng, g [,w, iw])
y = ode("discrete", y0, t0, t, f)
Arguments:
y0 : a real vector or matrix: initial state, at t0.
t0 : a real scalar, the initial time.
t : a real vector, the times at which the solution is computed.
f : an external function (Scilab function, list or string), computes the
value of f(t, y). It is the right hand side of the differential
equation. See f description section for more details.
type : a string, the solver to use. The available solvers are "adams", "stiff",
"rk", "rkf", "fix", "discrete" and "root".
rtol : relative tolerance on the final solution y (decimal numbers). If each is
a single value, it applies to each component of y. Otherwise, it must be
a vector of same size as size(y), and is applied element-wise to y.
atol : absolute tolerance on the final solution y (decimal numbers). If each is
a single value, it applies to each component of y. Otherwise, it must be
a vector of same size as size(y), and is applied element-wise to y.
jac : an external function (a Scilab fuction, list or string), computes the
Jacobian of the function f(t, y). See jacobian description section for
more details.
ng : an integer, number of components of g function
g : an external function (a Scilab fuction, list or string) with the syntax
g(t, y), returns a vector of size ng. Each component defines a surface.
Used ONLY with "root" solver. See ode_root help page.
y : a real vector or matrix. The solution.
rd : a vector available ONLY with "root" solver. See ode_root help page.
w, iw : real vectors. (INPUT/OUTPUT). See ode() optional output.
