WebThis covariance function is the rational quadratic kernel function, with a separate length scale for each predictor. It is defined as. k ( x i, x j θ) = σ f 2 ( 1 + 1 2 α ∑ m = 1 d ( x i m − x j m) 2 σ m 2) − α. You can specify the kernel function using the KernelFunction name-value pair argument in a call to fitrgp. WebC = cov (A,B) returns the covariance between two random variables A and B. If A and B are vectors of observations with equal length, cov (A,B) is the 2 -by- 2 covariance matrix. If A and B are matrices of observations, cov (A,B) treats A and B as vectors and is equivalent to cov (A (:),B (:)). A and B must be the same size.
