I have a column vector (20000 x 1) which is a 20 thousand entries long of numbers which are all decimals with 9 decimal places. I'm trying to find the mode of the column. This vector is called amps. I'm trying to find the mode of the column, but when I type in:

M = mode(amps);

It returns an error saying 'Subscript indices must either be real positive integers or logicals. '

Mean, median, var, and sum all work, but mode doesn't. What am I doing wrong?

I can't post code for legal reasons.

In MATLAB, when you create a variable with the same name as one of the MATLAB routines, you are unable to directly call the MATLAB routine by the same name until the variable is no longer in scope.

To put this more directly: you named a variable "mode", and you will need to rename that variable or else you will not be able to call the routine named "mode".
