Matlab cannot run a *.m file

I have an script named Cast_Analysis.m. I have already run it and it was working, but according to memory constraints the simulation was aborted. I had to restart Matlab but when tried to run it again Matlab keeps returning the following message:

Undefined function or variable 'Cast_Analysis'

I have tried to run it from the command window, from the run button in the editor tab and F5 button

The file, is stored under: C:\Users\emcirugedaroldan\Desktop\MatlabCoding\scripts\

i have checked that Matlab is able to find the file:

        >> exist('Cast_Analysis')
        ans =
             2

I have checked Matlab has rights to execute it

              >> fileattrib('Cast_Analysis.m')

                          Name: 'C:\Users\emcirugedaroldan\Desktop\MatlabCoding\scripts\Cast_Analysis.m'

                     OtherRead: NaN
                    OtherWrite: NaN
                  OtherExecute: NaN

I have checked Matlab finds the file in the specified directory

          >> what(pwd)

Can someone help me with it?

It is possible that there are multiple Mfiles with the same name on your MATLAB path? Try:

 which Cast_Analysis -all

[John D'Errico]

That would not cause the indicated error message though.

I'm wondering if the file was not closed properly when MATLAB crashed, thus somehow corrupted.

So you ran it, your program crashed, and when you started MATLAB and changed the current folder to the folder of Cast_Analysis.m, it says it's undefined? Does it still not run after a full reboot of the computer? Or no - it just ran one single time and after that it won't run at all, ever?

How are you trying to run it? The F5 key, the green triangle button on the tool ribbon, or typing the name onto the command line? Have you tried all 3 ways of running it?

Does the m-file require any input arguments?

Thanks,

Exactly, I ran it, Matlab crashed, reopen Matlab and tried to run it again --> undefined.

reboot computer, restarted Matlab, tried to run it --> undefined

created new file inside folder with new name, copied code, tried to run --> undefined

create new folder, copy file, tried to run --> undefined

the three ways, by code on comand line, by green button and by F5

no, no input arguments but calls to other functions

[John D'Errico]

You need to have that folder on your search path though. If you created a new folder, that new folder needs to be on the search path.

You can do that by using CD inside MATLAB to move to the new folder. Or you can use addpath or pathtool to add the folder to the path.
