Detailed Description
A single S-parameter array.
Member Function Documentation
◆ __attribute__() [1/2]
template<class T >
| SParameterVector::__attribute__ | ( | (noinline) | ) | const |
Loads the vector from a pair of waveforms in mag/angle format.
The waveforms may be sparse or uniformly sampled, but must be sampled at the same frequencies.
◆ __attribute__() [2/2]
template<class T >
| SParameterVector::__attribute__ | ( | (noinline) | ) | const |
Similar to ConvertFromWaveforms() but sets mag/angle values to zero indicating "no data".
The waveforms may be sparse or uniformly sampled, but must be sampled at the same frequencies.
