Hi,

I'm trying to calculate mean of a vector and getting a very odd answer. Here's the code:

rg_H25p0 = [29.0, 29.1, 29.5, 30.0, 30.1, 30.2, 30.3, 30.3, ...

30.3, 30.3, 30.4, 30.4, 30.4, 30.4, 30.4, 305., 30.6, 30.6, 30.7, ...

30.8, 30.9, 30.9, 31.1, 31.1, 31.1, 31.1, 31.1, 31.1, 31.4, 31.4, ...

31.4, 31.8];

mean_rg_H25p0 = mean(rg_H25p0)

Matlab keeps returning a mean of 39.1625, which is obviously impossible.

I used mean on a number of vectors and they all came out find, except for this one.

Any ideas?

You have a 305 in second row. I think it is supposed to be 30.5.

Okay. Yes, silly mistake.

Thanks!
