repl_diag_by_minus_sum_of_row=: 3 : 't-I*+/"1 t=.(-.I=.=/~i.#y)*y'
repl_diag_by_minus_sum_of_row=: 13 : 't-I*+/"1 t=.(-.I=.=/~i.#y)*y'
applying them to i.5 5 gives two different results with the 2nd giving an
unintended result
does anybody know why
the objective is to replace the diagonal in a square array by the sums of
the elements in their rows
cheers
