read_wave.m

Reads JCAMP-DX pulse waveform files. JCAMP-DX is a standard format in which pulse shaped are often distributed.

Syntax

    [A,phi,Cx,Cy,scaling_factor]=read_wave(filename,npoints)

Parameters

  filename   -   a string containing the name of the file

  npoints    -   waveform upsampling or downsampling is
                 performed to this number of points

Outputs

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

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

Put your own pulses into /kernel/pulses/pk_files; please also consider sending them to us.
