I get the following error:
Error loading /usr/local/MATLAB/R2021a/bin/glnxa64/builtins/shared_dastudio_builtins/mwdastudio_builtinimpl.so. libpangocairo-1.0.so.0: cannot open shared object file: No such file or directory
It turns out that the usage of the function /Applications/MATLAB_R2021b.app/toolbox/fixedpoint/fixedpoint/fi.m from the Fixed Point toolbox is causing the problem.
How can I overcome thos problem?

Hello Ido Lev,
I understand that you are encountering errors when using the ‘fi()’ function from the Fixed-Point toolbox.
Based on the error message, it seems that you are running MATLAB on a Linux environment and some required libraries are missing.
To overcome the problem, you can try the following steps:
  • Ensure that the necessary libraries are installed. Verify if the package ‘libpangocairo.1.0.so.0’ is installed on your system. On Ubuntu or Debian based systems, you can try installing the library by running the below command.
>> sudo apt-get install libpangocairo-1.0-0
  • Ensure that MATLAB can locate the library by setting the library search path to the library location on the system.
Please note that these steps are initial troubleshooting measures. They
may or may not resolve the issue.
Hope this information helps!
