parse mdf file in matlab

To parse an MDF file in MATLAB, you can use the mdfimport function provided by the MATLAB Data Acquisition Toolbox. This function reads MDF files into MATLAB and returns the data in a structure.

Here's an example code snippet that shows how to use mdfimport to read an MDF file and extract data from it:

main.m
% add MDF import library to MATLAB's path
addpath('C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmxPlugins\Common\mdf\matlab');

% read MDF file into MATLAB
data = mdfimport('filename.mdf');

% extract signals from the MDF data structure
time = data.(data.SignalNames{1}).TimeVector; % time vector
signal1 = data.(data.SignalNames{2}).Data; % first signal
signal2 = data.(data.SignalNames{3}).Data; % second signal

% plot signals
plot(time, signal1);
hold on;
plot(time, signal2);
legend('Signal 1', 'Signal 2');
xlabel('Time');
ylabel('Signal Value');

In this example, we first add the MDF import library to MATLAB's path using the addpath function. Then we use mdfimport to read the MDF file into MATLAB and store the data in a structure called data. We then extract the time vector and two signals from the data structure and plot them using the plot function.

Note that you need to replace filename.mdf in the code with the actual filename of the MDF file you want to read.
