matlab switch complex and real parts of a number -


i have column list of complex numbers (about 200k long). want switch real , imaginary parts. i'm pretty sure there single multiplication can accomplish this, can't find formula online. best way i've found far it's slow needs (it needs run realtime):

>> vec = [complex(1,11);complex(2,22);complex(3,33)]  vec =     1.0000 +11.0000i    2.0000 +22.0000i    3.0000 +33.0000i  >> complex(imag(vec),real(vec))  ans =    11.0000 + 1.0000i   22.0000 + 2.0000i   33.0000 + 3.0000i

i'm not sure if there built-in operation this, see speed increase not using complex function:

>> imag(vec) + real(vec)*1i ans =   11.0000 + 1.0000i   22.0000 + 2.0000i   33.0000 + 3.0000i

and way 

>> conj(vec)*1i ans =   11.0000 + 1.0000i   22.0000 + 2.0000i   33.0000 + 3.0000i

which think looks lot cleaner.
