Reads JCAMP-DX pulse waveform files. JCAMP-DX is a standard format in which pulse shaped are often distributed.
Contents
Syntax
[A,phi,Cx,Cy]=read_wave(filename,npoints)
Arguments
filename - a string containing the name of the file
npoints - waveform upsampling or downsampling is
performed to this number of points
Returns
A - polar amplitude at each slice phi - polar phase at each slice, radians Cx - Cartesian amplitude in X at each slice Cy - Cartesian amplitude in Y at each slice scaling factor - scaling factor for a given pulse shape
Examples
A few examples are distributed with Spinach, see /kernel/pulses/pk_files directory.
Notes
You can add your own pulse files to the same folder; please also consider sending them to us.
