is the mean function broken in R2014b

With just about any use of the mean function, i get this error message

   Subscript indices must either be real positive integers or
logicals.

I get this error using the example input matrix from docs. I create this matrix.

A = [0 1 1; 2 3 2; 1 3 2; 4 2 2]

Then run this command

M = mean(A)

Above error is generated.

All the other stats functions work as expected. Is this a bug in R2014b?

Is the workaround to write my own mean function?

Thanks,

Mike

"Is this a bug in R2014b?"

Nope. It is because you defined a variable named mean.

"Is the workaround to write my own mean function?"

Nope. The solution is to delete the variable named mean.

This has been discussed many times before:

etc. etc.

Tip for the future: whenever you have a problem with a function one of the first things you should do is check it using which.

You probably created a variable named mean, and are accidentally trying to access that variable.

I suggest either doing

clear mean

or just trying again with a freshly started instance of MATLAB.

Thanks to -multiple- folks with the right answer on this. I had created a standin variable named 'mean' for the function i'm writing.
