System object: dsp.LPCToLSF
Package: dsp
Convert LPC coefficients to line spectral frequencies
LSF = step(lpc2lsf,A)
[..., STATUS] = step(lpc2lsf,A)
Starting in R2016b, instead of using the step method
to perform the operation defined by the System
object™, you can
call the object with arguments, as if it were a function. For example, y
= step(obj,x) and y = obj(x) perform
equivalent operations.
LSF = step(lpc2lsf,A) converts
the LPC coefficients, A , to line spectral frequencies, LSF, in the range (0 pi). The System
object operates
along the columns of the input A.
[..., STATUS] = step(lpc2lsf,A) also
returns the status flag, STATUS,
indicating if the current output is valid when the ExceptionOutputPort property
is true.
obj specifies the System
object on
which to run this step method.
The object performs an initialization the first time the step method
is executed. This initialization locks nontunable
properties (MATLAB) and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System
object issues an error.
To change nontunable properties or inputs, you must first call the release method
to unlock the object.
