On my last assignment I set variables like Height = data_set1(:,1); and Mass = data_set1(:,2); with no issue. I am now trying to enter this in the editor:

load data_set2.dat

Column1: EMG data for vastus lateralis muscle of right leg.

Column2: EMG data for vastus lateralis muscle of the left leg.

R_emg = data_set2(:,1);

L_emg = data_set2(:,2);

I am receiving the message undefined function or variable 'R_emg' when I enter n = length (R_emg)

I have no idea why. The command worked last week.

Please post the code you are are using.

Also, you should always use the S=load(__) syntax which will load the variables into a struct. Then it is clear where variables come from and it becomes possible to track down where an issue might originate from.
