isLocked

System object: dsp.AudioFileReader
Package: dsp

Locked status for input attributes and nontunable properties

Syntax

y = isLocked(H)

Description

y = isLocked(H) returns the locked state, Y, of the AudioFileReader object.

The isLocked method returns a logical value that indicates whether input attributes and nontunable properties for the object are locked. The object performs an internal initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. After locking, the isLocked method returns a true value.
