Construct complex fi object from real
and imaginary parts
c = complex(a,b)
c = complex(a)
c = complex(a)
The complex function constructs a complex fi object
from real and imaginary parts.
c = complex(a,b) returns the complex result a
+ bi, where a and b are
identically sized real N-D arrays, matrices, or scalars of the same
data type. When b is all zero, c is
complex with an all-zero imaginary part. This is in contrast to the
addition of a + 0i, which returns a strictly real
result.
c = complex(a) for a real fi object a returns
the complex result a + bi with real part a and
an all-zero imaginary part. Even though its imaginary part is all
zero, c is complex.
c = complex(a) returns the complex equivalent
of a, such that isreal(c) returns
logical 0 (false). If a is real, then c is a
+ 0i. If a is complex, then c is
identical to a.
The output fi object c has
the same numerictype and fimath properties
as the input fi object a.
