Interface rms_diff

Root-mean-square difference calculation for components of two vectors or arrays. For two vectors of $N$ dimensions, this is calculated as

$$\sum_{i=1}^{N} \left(\mathbf{v_1}_i - \mathbf{v_2}_i\right)^2$$

For two arrays of dimension $N \times M$, this is calculated as

$$\sum_{j=1}^{M} \sum_{i=1}^{N} \left(\mathbf{a_1}_{ij} - \mathbf{a_2}_{ij}\right)^2$$

vector1, vector2 -- real(dp), intent(in), dimension(:)

array1, array2 -- real(dp), intent(in), dimension(:,:)

Return value -- real(dp)
