Calling Sequence

Verify(sys)

Parameters

sys

-

System; system object to verify

Description

• 

The Verify command checks the validity of sys, a linear system object.

• 

If the system object is verified, the procedure returns NULL. Otherwise an error message describing the problem is displayed. For some problems, a warning rather than an error is generated.

Verification Criteria

For a system to be verified, it must meet the following criteria.

• 

It must be a module.

• 

It must have the exports common to all the system types.

• 

It must have the Matrix exports specific to its type.

• 

The Matrix exports must have compatible dimensions and correspond to the number of input, output, and, possibly, state variables.

• 

The Matrix elements must be of the appropriate type and correspond to a valid linear system.

Verifysys

Make the transfer function an expression that is not a rational polynomial in s.

sys:-tf1,1ⅇss3+5s2+7s+6

tf1,1:=ⅇss3+5s2+7s+6
