Synopsis#include <flint/arb_mat.h>
void arb_mat_exp_taylor_sum(arb_mat_t S, const arb_mat_t A, slong N, slong prec)source

Sets S to the truncated exponential series \sum_{k=0}^{N-1} A^k / k!, using rectangular splitting with O(\sqrt{N}) matrix multiplications. The factorials are generated by their recurrence so that the scalars are small integers, and the divisions are postponed by computing partial factorials of length O(\sqrt{N}) [Joh2014b].
