Computing Ochiai Distance Matrix with Pairwise Deletion in R Using Vegan Package

The provided code demonstrates how to calculate the result of multiplying two matrices, `-M1` and `B`, where `M1` is calculated by multiplying a first matrix with a second matrix, and then taking the negative of that result. The resulting matrix from this operation can be obtained either directly or through an intermediate step involving another multiplication with a third matrix (`B`) to ensure equivalence.
