Hi @SREETHU S,

The function "trimr" does not exist as an inbuilt function in MATLAB.

The reason why the code does not give an error might be because it has a declaration of a function with the name "trimr". Please refer to the codebase you have, you should find the function.

Hope this helps!

The code for trimr is shown in https://www.mathworks.com/matlabcentral/answers/452463-functions-may-be-used-incompatibly-or-redefined

It is a local function, declared as a second function inside a .m file. As such it is not directly callable outside of the .m file.

In order to be callable outside of the .m file it is inside, the first function in the .m file would have to create a handle to the trimr function and pass out the handle.
