y = s0norm(f); y = s0norm(f,...);
s0norm(f) computes the \(S_0\)-norm of a vector.
If the input is a matrix or ND-array, the \(S_0\)-norm is computed along the first (non-singleton) dimension, and a vector of values is returned.
WARNING: The \(S_0\)-norm is computed by computing a full Short-time Fourier transform of a signal, which can be quite time-consuming. Use this function with care for long signals.
s0norm takes the following flags at the end of the line of input parameters:
| 'dim',d | Work along specified dimension. The default value of [] means to work along the first non-singleton one. |
| 'rel' | Return the result relative to the \(l^2\) norm (the energy) of the signal. |
