Detect finite elements of array



TF = isfinite(A) returns an array the same size as A containing logical true (1) where the elements of the array A are finite and logical false (0) where they are infinite or NaN. For a complex number z, isfinite(z) returns 1 if both the real and imaginary parts of z are finite, and 0 if either the real or the imaginary part is infinite or NaN.

For any real A, exactly one of the three quantities isfinite(A), isinf(A), and isnan(A) is equal to one.
