Generating Random Numbers from Multivariate Normal Distributions with Non-Positive Definite Covariance Matrices in R

Sorting Matrix Values with Zeros in Ascending Order without Affecting "Zero" in R: A Step-by-Step Solution

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.
