) and a constant
(<tt>meanConst</tt>) to get an affine function. Note, how the
different components are composed using cell arrays. The hyperparameters
for the mean are given in <tt>hyp.mean</tt> and consists of a single
(because the input will one dimensional, i.e. <tt>D=1</tt>) slope (set
to 0.5) and an off-set (set to 1). The number and the order of these
hyperparameters conform to the mean function specification. You can
find out how many hyperparameters a mean (or covariance or likelihood
function) exp
