Define a param structure

Module

• xcos

params

Size : 11.

Type : scilab list.

• wpar This vector is not currently used. It may be used in the future to code window sizes of the editor. Size : 6. 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:

  • atol Integrator absolute tolerance for the numerical solver.
  • rtol Integrator relative tolerance for the numerical solver.
  • ttol Tolerance on time. If an integration period is less than ttol, the numerical solver is not called.
  • 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
  • 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.
  • solver Choice of numerical solver. The value 0 implies an ODE solver and 100 implies a DAE solver.
  • hmax Maximum step size for the numerical solver. 0 means no limit.

  Size : 7. Type : column vector of real.

• tf Final time simulation. The simulation stops at this time. The default value is 100000. 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. The fields are the following:

  • 3D A list with two entries. The first one is a boolean indicating whether or not blocks should have 3D aspect. The second entry indicates the color in the current colormap to be used to create the 3D effect. The default is 33 which corresponds to gray added by Scicos to the standard colormap, which contains 32 colors. The default value is list(%t,33).
  • Background Vector with two entries: background and foreground colors. The default value is [8,1].
  • link Default link colors for regular and activation links. These colors are used only at link construction. Changing them does not affect already constructed links. The default value is [1,5], which corresponds to black and red if the standard Scilab colormap is used.
  • ID A list of two vectors including font number and sizes. The default value is [5,1],[4,1].
  • Cmap An n,3 matrix containing RGB values of colors to be added to the colormap. The default value is, [0.8,0.8,0.8] i.e., the color gray.

  Size : 6. Type : scilab tlist of type scsopt.

• void2 unused field. Size : -. Type : -.

• void3 unused field. Size : -. Type : -.

• doc User defined diagram documentation structure. Size : 1. Type : Strings.
