scicos_params
Define a param structure
params
Diagram configuration values. Some of the value are graphical information, others directly configure the simulator.
Type : scilab tlist of type "params" with fields :
wpar,
title,
tol,
tf,
context,
void1,
options,
void2,
void3 and
doc.
wpar
This vector is not currently used. It may be used in the future to code window sizes of the editor.
Type : column vector or real.
title
Vector of character strings, where the first one is the diagram title and default name of save file name, and the second one is the path of the directory of the file name.
Size : 2.
Type : row vector of strings.
tol
A vector containing simulation parameters including
various tolerances used by the solver. This vector is composed of : [ atol , rtol , ttol , deltat , scale , solver , hmax ] where :
(1) atol
Integrator absolute tolerance for the numerical solver.
(2) rtol
Integrator relative tolerance for the numerical solver.
(3) ttol
Tolerance on time.
If an integration period is less
than ttol, the numerical solver is not called.
(4) deltat
Maximum integration time interval.
If an integration period is larger than
deltat, the numerical solver is called more than
once in such a way that for each call the integration
period remains below deltat.
(5) scale
Real-time scaling; the value 0 corresponds to no
real-time scaling.
It associates a Scicos simulation time to the real time in seconds.
A value of 1 means that each Scicos unit of time
corresponds to one second.
A value of 0.5 means that each Scicos unit of time
corresponds to 500 milliseconds.
(6) solver
Choice of numerical solver.
The value 0 implies an ODE solver and 100
implies a DAE solver. See also : Solvers comparisons
(7) hmax
Maximum step size for the numerical solver.
0 means no limit, let the solver use its own time predicate.
Size : 7.
Type : column vector of real.
tf
Final time simulation. The simulation stops at this time.
Size : 1.
Type : real.
context
A vector of strings containing Scilab instructions defining Scilab variables to be used inside block's dialog box as symbolic parameters.
All valid Scilab instructions can be used and also comments.
Size : number of lines of the context.
Type : column vector of strings.
void1
unused field.
Size : -.
Type : -.
options
Scilab object of type "scsopt" defining graphical properties of the editor such as background color and link color.
Type : scilab tlist of type "scsopt" with fields :
3D,
Background,
link,
ID and
Cmap
3D
Not used.
Background
Vector with two entries: background and foreground colors as Scilab colors.
The default value is [8,1].
link
Not used.
ID
Not used.
Cmap
Not used.
void2
unused field.
Size : -.
Type : -.
void3
unused field.
Size : -.
Type : -.
doc
User defined diagram documentation structure.
Size : 1.
Type : Strings.
