GPU part of calculation of Matern 3/2 kernel.
This function is for the cross covariance matrix needed to compute the posterior predictive density.
[in] | x1 | first input vector or matrix |
[in] | x2 | second input vector or matrix |
[out] | res | squared distances between elements of x |
sigma_sq | squared standard deviation | |
root_3_inv_l | sqrt(3.0) / length_scale | |
size1 | number of elements in x1 | |
size2 | number of elements in x2 | |
element_size | the number of doubles that make one element of x and y |
