rmsd {fungible} | R Documentation |
Calculates the root mean squared deviation of matrices A and B. If these matrices are symmetric (Symmetric = TRUE) then the calculation is based on the upper triangles of each matrix. When the matrices are symmetric, the diagonal of each matrix can be included or excluded from the calculation (IncludeDiag = FALSE)
rmsd(A, B, Symmetric = TRUE, IncludeDiag = FALSE)
A |
A possibly non square matrix. |
B |
A matrix of the same dimensions as matrix A. |
Symmetric |
Logical indicating whether A and B are symmetric matrices. (Default: Symmetric = TRUE) |
IncludeDiag |
Logical indicating whether to include the diagonals in the calculation. (Default: IncludeDiag = FALSE). |
Returns the root mean squared deviation of (A - B).
