PeakmagnitudetoRMS ratio
Y = peak2rms(X)
Y = peak2rms(X,DIM)
returns
the ratio of the largest absolute value in Y
= peak2rms(X
)X
to
the rootmeansquare (RMS) value of X
. peak2rms
operates
along the first nonsingleton dimension of X
.
For example, if X
is a row or column vector, Y
is
a realvalued scalar. If Y
is an NbyM matrix
with N>1, Y
is a 1byM row vector containing
the peakmagnitudetoRMS levels of the columns of Y
.
computes
the peakmagnitudetoRMS level of Y
= peak2rms(X
,DIM
)X
along the
dimension, DIM
.
