I've tried using the readtable function T = readtable('myfile.csv') for a specific .csv file I'm trying to import but whenever I try to run the section I get this error message:
Error using readtable (line 498)
Unable to find or open 'Rho_ISA.csv'. Check the path and filename or file permissions.
Error in untitled (line 1)
T = readtable('Rho_ISA.csv')
How do I fix this?

The message is clear: "Unable to find or open 'Rho_ISA.csv'"
This means, that this file is not found in the current folder. So simply provide the path to the file also:
Folder = 'C:\Your\Folder'; % Adjust for your needs
T = readtable(fullfile(Folder, 'Rho_ISA.csv'))

Sorry I've tried to adjust the code but the same error message is coming up. This is what I've done:
Assignment = 'C:\Assignment';
T = readtable(fullfile(Assignment,'Rho_ISA.csv'));

The the error message tells you, that the folder "C:\Assignment" does not contain a file called "Rho_ISA.csv".
Try it:
Assignment = 'C:\Assignment';
isfile(fullfile(Assignment, 'Rho_ISA.csv'))
Maybe the file name does not contain an "I" (uppercase i) but an l (lowercase L). Or you hide the file extension and the real file is called "Rho_ISA.csv.xls".
In any way, this is not a problem of readtable(), but the file is missing.
