I am trying to read a basilar table in MATLAB.
I wrote some scripts and I had no problem until version 2020a, where I see that there are huge changes in tables management functions.
Here are the call to readtable that I always use:
readtable(devices_file, 'Delimiter', ',', 'Format','%q%q')
Starting from R2020a, the readtable fails with this strange error:
Error using readtable (line 318)
Undefined function 'isnan' for input arguments of type 'string'.
Note: readtable detected the following parameters:
'HeaderLines', , 'ReadVariableNames', true
Also readtable with no arguments fails. I inspected into the core and the fail seems to go deep and it is correlated to DelimitedTextImportOptions or some other similar function.
Using detectImprtOptions the error is similar:
detectImportOptions(devices_file, 'Delimiter', ',', 'Format','%q%q')
also here its the same omitting the arguments.
Check for incorrect argument data type or missing argument in call to function 'isnan'.
Error in detectImportOptions (line 381)
Do you know how to workaround this issue or if it is a bug that has to be resolved?
