You might want to reconsider Mata. The syntax is no more complicated, and there are several advantages to doing numerical computations in Mata, with a small overhead: ********************************** matrix def A = (0.5, 0.25)' matrix def B = (10, 0.5 \ 0.5, 15) mata: st_matrix("C", /// C=lusolve(st_matrix("B"), st_matrix("A"))) mat li C ********************************** You might also want to read this excellent post by Bill Gould: http://www.stata.com/statalist/archive/2011-02/msg00376.html Unless of course you are constrained by your Stata version...
