Arguments

SystemOutputChatacteristicsNames

Array of names of system output characteristics in xcos-diagram (see block TOWS_c). Array dimension 1xM

SystemOutputCharacteristicsIndexes

An array of indices of the dynamics of the output characteristics in the names of the output characteristics of the system in the xcos diagram (block TOWS_c), the index of each name of the output characteristic of the system in the array SystemOutputChatacteristicsNames is set by the corresponding element array SystemOutputCharacteristicsNamesIndexes. Array dimension 1xM

SystemShemaName

Full name of the user system xcos diagram file (extension .zcos, .xcos)

SystemOutputCharacteristicsCompressionFunctions

Cell array (see cell arrays) functions for getting the parameters of computed dynamics, specified by SystemOutputCharacteristicsIndexes

SystemParametrsNames

The names of the system parameters in the xcos diagram (see the context property in Xcos diagram structure). Array of strings of dimension 1xM

SystemParametrsValues

System parameter values in the xcos diagram (see the context property in Xcos diagram structure), specified by the corresponding SystemParametrsNames. NxM array of real numbers (each n-th row of N rows in the matrix is the corresponding n-th dynamics)

absolutTolErr

Absolute errors of integration in xcos (see the tol (1) atol property in Xcos diagram structure) of each dynamics. Array of positive real numbers of dimension 1xN

relativeTolErr

Relative errors of integration in xcos (see the tol (2) rtol property in Xcos diagram structure) of each dynamics. Array of positive real numbers of dimension 1xN

Solver

Solver views in xcos (see the tol (6) solver property in Xcos diagram structure) of each dynamics. An array of integers ranging from 0 to 100 - solver codes. The dimension of the solver codes is 1xN

toleranceTime

Time errors in xcos are the corresponding minimum steps of integration over time (see the tol (3) ttol property in Xcos diagram structure) for each dynamics. Array of positive real numbers of dimension 1xN

Return values

SystemOutputChatacteristics

Matrix of parameters of system output characteristics. Dimension of matrix PxN

Description

Simulates (computational experiment) a user system, specified in the form of an xcos diagram, for its various parameters (specified in the context).

Returns a matrix of speaker parameters with user-defined output characteristics of the system (in the diagram, these are given as TOWS_c blocks)
