I am tryng to use cwt function from Wavelet toolbox.
I am using the example provided in the description:
https://ch.mathworks.com/help/wavelet/ref/cwt.html
However, I get the following mistake:
load mtlb;
w = cwt(mtlb);
Error using cwtfilterbank/validateInputsMATLAB
Error: File: strncmpi.m Line: 1 Column: 1
Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII
characters.
Why does this mistake come?

The stack trace mentioned usually comes up, whenever there is a use of special character in a “.m” script.
In order to DEBUG this further, please follow the below mentioned procedure:
  • Check if “load mtlb” does not precede with any special character. See the code below, that would cause the trace mentioned.
`load mtlb;
w = cwt(mtlb);
  • Name of your “.m” script must not match with any predefined MATLAB module, “strncmpi” is a built-in module, make sure you are not making any changes in that.
