Owning Palette: Stochastic Systems VIs

Installed With: Control Design and Simulation Module

Determines if the dimensions of the stochastic state-space system matrices are consistent with each other. This VI also calculates the number of inputs, outputs, and states, as well as the dimensions of the process noise vector w.

Stochastic State-Space Model In specifies a mathematical representation of a stochastic system.

Required Matrices specifies the system matrices that this VI requires to continue execution.

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use exception control to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Stochastic State-Space Model Out returns the model after this VI verifies the stochastic properties.

Number of States returns the number of states in the system model.

Number of Inputs returns the number of inputs in the system model.

Number of Outputs returns the number of outputs in the system model.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

Dimension of Process Noise returns the length of the process noise vector w.
