That is similar to the example:
octave:20> z = complex([1 2 3],[1 0 2])
z =
1 + 1i 2 + 0i 3 + 2i
octave:21> isreal(z)
ans = 0
octave:22> isreal(z(1))
ans = 0
octave:23> isreal(z(2))
ans = 1
octave:24> whos z z(1) z(2)
Variables in the current scope:
Attr Name Size Bytes Class
==== ==== ==== ===== =====
c z 1x3 48 double
c z(1) 1x1 16 double
z(2) 1x1 8 double
Total is 5 elements using 72 bytes
...
Interchanging the square and curved parentheses is another, simpler
illustration:
octave:28> iscomplex(complex(1,0))
ans = 1
octave:29> iscomplex([complex(1,0)])
ans = 0
