isinf
tests for infinite elements
Syntax
r = isinf(x)
Arguments
- x
matrix of real or complex numbers
- r
matrix of booleans of the same size as
x
Description
isinf(x)
returns the matrix r
of booleans such that, for each element x(i)
,
r(i)
is set to %T
if and only if
x(i)
is infinite.
When x
is complex-encoded, x(i)
is considered infinite if its real part or its imaginary part (or both)
are infinite.
Examples
[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])
