factor-like output |
Hello! I wrote a function for factorization of binomial coefficients. I want it to output result as t_MAT, just like factor(). And I can't figure out how to make it. My code uses forprime for primes in some range and determines exponents of prime factors. Then it stores prime and its exponent as a vector, which I intend to append to resulting factorization matrix: (pseudocode) factors=Mat; forprime(p=a,b, \\ ... there goes the logic of checking prime and determination of its exponent v = [p, p_e]; factors.append(v) ); return factors; I need to add vector rows to matrix dynamically, but if I make something like that: m=Mat v1=[1, 2] v2=[3, 4] m=matconcat(v1) m=matconcat(v2), m becomes [3, 4], missing first vector. On the other hand, matrix() doesn't allow adding values dynamically. Please help. Best regards,
