what is the difference between .mdl and .slx files and full form of mdl and slx?

what is the difference between .mdl and .slx files and full form of mdl and slx?

Answer 1

[Sebastian Castro]

.mdl is the legacy file format. Simulink models switched to the newer .slx format in 2012.

Whereas .mdl files are single text files, .slx files are compressed packages. You can find more at https://www.mathworks.com/help/simulink/ug/saving-a-model.html#btbr7kx-1

[Bhuwan Bisht]

SLX is a compressed package that conforms to the Open Packaging Conventions (OPC) interoperability standard. SLX stores model information using Unicode® UTF-8 in XML and other international formats. Saving Simulink models in the SLX format:

• Typically reduces file size compared to MDL. The file size reduction between MDL and SLX varies depending on the model.
• Solves some problems in previous releases with loading and saving MDL files containing Korean and Chinese characters.
• Enables incremental loading and saving. Simulink optimizes performance and memory usage by loading only required parts of the model and saving only modified parts of the model.
