  "Description": "Creates a wrapper for the 'SuiteSparse' routines that\nexecute the Takahashi equations. These equations compute the\nelements of the inverse of a sparse matrix at locations where\nthe its Cholesky factor is structurally non-zero. The resulting\nmatrix is known as a sparse inverse subset. Some helper\nfunctions are also implemented. Support for spam matrices is\ncurrently limited and will be implemented in the future. See\nRue and Martino (2007) <doi:10.1016/j.jspi.2006.07.016> and\nZammit-Mangion and Rougier (2018)\n<doi:10.1016/j.csda.2018.02.001> for the application of these\nequations to statistics.",
