core_dcmg - Generate covariance matrix A in dense format between two sets of locations (l1, l2) (Matern Kernel). The routine makes only one pass through the tile A. One tile operation.

Parameters

[out]	A	The m-by-n matrix on which to compute the covariance matrix.
[in]	m	The number of rows in the tile A.
[in]	n	The number of cols in the tile A.
[in]	m0	Global row index of the tile A.
[in]	n0	Global col index of the tile A.
[in]	l1	Location struct of the first input.
[in]	l2	Location struct of the second input.
[in]	localtheta	Parameter vector that is used to generate the output covariance matrix.
[in]	distance_metric	Distance metric "euclidean Distance (ED) ->0" or "Great Circle Distance (GCD) ->1"
