"unable to resolve the name" error while using readmatrix function

Hi,

I've got this error message while running a program in MATLAB 2020b:

Error using readmatrix: Unable to resolve the name matlab.io.internal.functions.FunctionStore.getFunctionByName.

Previously in 2020a version I had no problem using the program with readmatrix...

I appreciate any idea why it is happening.

What shows up for

ls(fullfile(matlabroot, 'toolbox/shared/io/general/+matlab/+io/+internal/+functions/FunctionStore.m'))

If it says the directory does not exist then you have a corrupted version of MATLAB for sure. The directory should have 11 files in in R2020b.

Hi @Sharare,

It could be because some file in your current working directory or MATLAB search path is conflicting with MATLABs inbuilt files. Check if you have a file named “readmatrix.m” in your current working directory or in your MATLAB search path.

That particular error message would not show up if the user had their own readmatrix; that is an accurate copy of the name of nearly the only function called by readmatrix.m in R2020b
