Inversion in sgp_negloglik_givenC

[CielAl]

For the negative log likelihood, the term fn.'/C*fn pops an exception: " Error using / Matrix dimensions must agree. " in Matlab R2016b.

fn is a scalar here.

Could that be a potential bug?

OK it seems like my input of fN was arbitrary, hence the dimensions did not agree. That won`t be an issue if all functions are correctly involked.
