always about positive definite matrix
...is basic idea. 4. I recommend in the summary you mention nearPD but not posdefify, because nearPD was written more recently using the results of research not available to the authors when posdefify was written. MARTIN: There is a typo in the first line of the documentation for "symmpart". It currently reads, "symmpart(x) computes the symmetric part (x + t(x))/2 and the skew symmetric part (x - t(x))/2 of a square matrix x.". It should read, "symmpart(x) computes the symmetric part (x + t(x))/2 and skewpart the skew symmetric part (x - t(x))/2 of a square...

gdistance::shortestPath throws error "not a symmetric matrix"
Hi, Calling gdistance::shortestPath gives me the error Error in asMethod(object) : not a symmetric matrix; consider forceSymmetric() or symmpart() The output of dput(.traceback()) is pairlist("stop(\"not a symmetric matrix; consider forceSymmetric() or symmpart()\")", "asMethod(object)", "as(Laplacian,\"symmetricMatrix\")", ".Laplacian(x)", ".flowMap(x, ci, cj, tc)&q...

"The Matrix" is approaching version 1.0-0
...t; of all(!) kinds of S/R indexing and some new generic functions such as lu() {LU decomposition} Schur(), BunchKaufman(), norm(), rcond() {Matrix norms and condition numbers} expm() {Matrix exponential}, band(), triu(), tril() {extract band-diagonal or triangular sub-matrices} symmpart(), skewpart() { (x + t(x))/2 and (x - t(x)) / 2 } are provided. Further, an extension to the xtabs function xtabs(*, sparse=TRUE) for large sparse, two-way contingency tables and coercion of one *factor* (possibly crossed with one <numeric>) to the corresponding (potentially huge) spar...
