peak2peak

Compute signal maximum to minimum differences.

Syntax

r = peak2peak(x)

r = peak2peak(x,dim)

Inputs

x
Data sample.
Type: double
Dimension: scalar | vector | matrix
dim
Dimension on which to perform the calculation.
Default: first non-singleton dimension.
Type: integer
Dimension: scalar

Outputs

r
Peak to RMS differences.

Examples

Vector example:

x = [9.3, 10.6, 13.3, 15.1, 18.2, 11.9];
r = peak2peak(x)
r = 8.9
Matrix example:
x = [9.3, 4.8; 10.6, 6.6; 11.9, 8.0; 13.3, 9.3; 15.1, 10.6; 18.2, 11.9];
r = peak2peak(x)
r = [Matrix] 1 x 2
8.90000  7.10000

Comments

The function computes the difference of the maximum value to the minimum value for each vector in x along the dimension of interest.

For complex signals, peak magnitudes are considered.
