fm_row_kron

Takes two Matrices and computes the row-wise Kronecker product. Optionally
applies row-wise weights and/or applies an additional 0/1 row-wise Kronecker
matrix product.

Generate planar and spherical triangle meshes,
compute finite element calculations for 1- and 2-dimensional flat and curved
manifolds with associated basis function spaces, methods for lines and
polygons, and transparent handling of coordinate reference systems and
coordinate transformation, including 'sf' and 'sp' geometries. The core
'fmesher' library code was originally part of the 'INLA' package, and
implements parts of "Triangulations and Applications" by
Hjelle and Daehlen (2006) <doi:10.1007/3-540-33261-8>.
