A Simple Way to Specify Symmetric, Block Diagonal Matrices

v1.0.3 · Mar 11, 2026 · GPL (>= 2)

Description

Provides a simple mechanism to specify a symmetric block diagonal matrices (often used for covariance matrices). This is based on the domain specific language implemented in 'nlmixr2' but expanded to create matrices in R generally instead of specifying parts of matrices to estimate. It has expanded to include some matrix manipulation functions that are generally useful for 'rxode2' and 'nlmixr2'.
