=== Matlab ===
Please, read the instructions on the GitHub labstreaminglayer website (https://github.com/labstreaminglayer/liblsl-Matlab) on how to prepare Matlab to work with LSL. You can either use the latest release for your Matlab version, or if that doesn't workout well, build it from the source files. Make sure to add the liblsl-Matlab folder to your path recursively to make it available to your own scripts.
A short example for sending lsl streaming data:
<syntaxhighlight lang="matlab" line>
%% instantiate the library
disp('Loading library...');
lib = lsl_loadlib();
% make a new stream outlet
disp('Creating a new streaminfo...');
info = lsl_streaminfo(lib,'BioSemi','EEG',8,100,'cf_float32','sdfwerr32432');
disp('Opening an outlet...');
outlet = lsl_outlet(info);
% send data into the outlet, sample by sample
disp('Now transmitting data...');
while true
outlet.push_sample(randn(8,1));
pause(0.01);
end
