Hi matlab users: I was trying to run a code in which I loaded a .mat file called cefff10.mat. I had this error mentioned in the title and I am sure the .mat exists in the same folder as the code and the its name is written correctly with lowercase letters, what could be the problem? I am so confused, any help? thanks

cefff10.mat &nbsp is the name of a file.
Run
whos -file cefff10.mat
to learn which variables is in that file. And read the help on load

oh, it turned out that the mat file is still named with the previous name even though I changed its name. I fixed this issue by keeping its previous name Ceff10 not Cefff10.

MATLAB is case-sensitive, so ceff10 is not the same as Ceff10. Change all references from ceff10 to Ceff10 and you shouldn’t have any more problems with it. Check your other variables as well.
