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.
