Simulink blocks do not have .m files, except for the case that you can register a .m file as an S function. The S function block is what would appear in the Simulink diagram, but in that case there would be a backing .m file.

In particular, MATLAB Function Blocks do not have .m files; the code is stored as part of the model, and can be read by "explore" the node and looking at its properties.

If you are looking for the implementation of https://www.mathworks.com/help/dsp/ref/lmsfilter.html then it is inside a .p file.

i cant find node in "explore" .... and not even .p file in https://www.mathworks.com/help/dsp/ref/lmsfilter.html

can you help me in this

[Walter Roberson]

toolbox/dsp/dsp/compiled/+dsp/en/LMSFilter.m --> class properties definition only

toolbox/dsp/dsp/compiled/+dsp/LMSFilter.p --> implementation

toolbox/dsp/dsp/compiled/+dspcodegen/LMSFilter.p --> implementation used for code generation

[Ali Mukhtar]

i got the files but it is asking to delete the p-file or run the p code function on this file

[Walter Roberson]

.p files are files that Mathworks has deliberately encoded to not be readable. They actively do not want you to read that source code.
