			==Matlab Example==

			*Open a stream to the EyeSeeCam

			type = 'EyeSeeCam @ dcn-pl04';
			name = 'EyeSeeCam SCI Data';
			lslString = sprintf('type= ''%s'' and name= ''%s''', type, name);
			info=lsl_resolver(lslString);
			lslStream = lsl_istream(info{1});

			*Open a session and add the stream to the session.

			session = lsl_session;
			session.add_stream(lslStream);

			*Start and stop the session and get the data from the stream.

			session.start;
			....wait some time....
			session.stop;
			data = lslStream.read;

			In the directory <...biofysica\liblsl\liblsl-Matlab\examples> you can find more examples (with descriptions in the readme.md file).

	*Real-time Data Streaming: LSL allows the continuous and real-time transmission of data from various sources, such as sensors, recording devices, and software applications. This can include EEG, ECG, eye-tracking data, motion capture, and more.		*Real-time Data Streaming: LSL allows the continuous and real-time transmission of data from various sources, such as sensors, recording devices, and software applications. This can include EEG, ECG, eye-tracking data, motion capture, and more.

	*Data Synchronization: LSL provides a mechanism for synchronizing data streams from multiple devices or applications~~. This synchronization is essential for conducting experiments or analyses that require precise temporal alignment across different data sources~~.		*Data Synchronization: LSL provides a mechanism for synchronizing data streams from multiple devices or applications.

	*Cross-Platform Support: LSL is platform-independent and can be used on various operating systems, including Windows, macOS, and Linux~~. This makes it versatile and suitable for a wide range of research environments~~.		*Cross-Platform Support: LSL is platform-independent and can be used on various operating systems, including Windows, macOS, and Linux.

	*Language Support: LSL offers libraries and bindings for several programming languages, including Python, C/C++, Java, MATLAB ~~(which you are familiar with)~~, and others~~. This allows researchers to integrate LSL into their existing workflows and data processing pipelines~~.		*Language Support: LSL offers libraries and bindings for several programming languages, including Python, C/C++, Java, MATLAB, and others.

	*Flexible Data Types: It supports various data types, including numeric, string, and marker data, making it adaptable to different types of experiments and data formats.		*Flexible Data Types: It supports various data types, including numeric, string, and marker data, making it adaptable to different types of experiments and data formats.

	*Open Source: LabStreamingLayer is an open-source project, which means it is continuously developed and improved by a community of researchers and developers~~. This openness encourages collaboration and customization~~.		*Open Source: LabStreamingLayer is an open-source project, which means it is continuously developed and improved by a community of researchers and developers.

	*Network Capabilities: LSL supports both local data streaming (within a single computer) and network-based streaming~~, enabling data sharing across different devices and locations~~.		*Network Capabilities: LSL supports both local data streaming (within a single computer) and network-based streaming.

	*Timestamps: LSL provides high-precision timestamps~~, allowing researchers to accurately timestamp events and data samples~~.		*Timestamps: LSL provides high-precision timestamps.
