This does not work on .wfm files produced by my Rigol 1104B. Does anyone know the file format for the 1104?

H Paul,

many thanks for distributing this very well programmed Rigol waveform reader.
This works like a charm.

Maybe a small example file like the lines below would enable inexperienced users to extract the full functionality of your great work quicker:

________________
%% PlotRigolWaveform
clear all; clc;
% reads wfm file
[y, nfo] = readRigolWaveform('b.wfm');
% Creates an time array based on the details in "nfo"
TIME=linspace(nfo.x0,nfo.x0+nfo.dx*length(y),length(y));
% plots all available traces along TIME axis
plot(TIME,y)
_______________

Feel free to recycle that if you wish.
Many thanks,
Tobi
