r = isinf(x)
матрица или вектор вещественных или комплексных значений
вектор или матрица логических значений
isinf(x) returns a matrix r
of booleans such that, for each element x(i),
r(i) is set to %T as soon as
x(i) is infinite.
When x is complex-encoded, x(i)
is considered infinite as soon as its real or imaginary or both parts
are infinite.
[i, inf, nan] = (%i, %inf, %nan); isinf([-1 0.01 -inf inf nan]) isinf([2+i, -10-inf, inf+i]) isinf([nan-i, inf-nan*i, nan+i*inf]) | | |
