clean y. to tolerance of x. (default 1e_10) form: tolerance (default 1e_10) clean numbers sets values less than tolerance to 0
sum data columns of matrix by key form: key colsum mat sum data columns of matrix on key columns e.g. if column 2 of mat is age, then 2 colsum mat sums the remaining columns by age
group indices of y. in x. Return group indices of elements of y. x. is an integer vector of the starting numbers of each group, assumed to be in ascending order. e.g. 0 0 0 1 1 1 2 2 = 0 3 6 groupndx i.8 i.e. <:@(+/@(<:/))
solves recurrence r(i)=a(i)+r(i-1)*m(i-1) form: r = m recur a r(0) = a(0) r(i) = a(i)+r(i-1)*m(i-1) e.g 1.05 1.10 recur 100 100 100 100 205 325.5
round y. to nearest x. preserving total distributive rounding round y. to nearest x. preserving total to nearest x. e.g. 0.1 rounddist 6$0.45 0.5 0.5 0.5 0.4 0.4 0.4
steps from a to b in c steps form: steps a,b,c
