WebIt invokes as many separate Mathematica evaluations as the length of the diagonal. It will unpack packed Real arrays when written like this because it assigns 0 instead of 0.0 . A better solution would explicitly need to check for packed arrays, detect their type (integer or real/complex) and assign the appropriate element. WebUpdated in 13.1. Minors [ m] gives the minors of a matrix m. Minors [ m, k] gives the k minors. Minors [ m, k, f] applies the function f rather than Det to each of the submatrices picked out.
