Becarefulwhentakingthetransposeofcomplexmatrices. Thetranspose
operator takes the complex conjugate transpose. If
z
is the matrix:
1
i
0+2
i
1+
i
0
−
then
z'
is:
1
.
0

To take the transpose without conjugating the complex elements, use
the

operator. In this case
z.'
is:

4 Basic Graphics
The bread-and-butter of matlab graphics is the
plot
command. Earlier
we produced a plot of the sine function:
x = 0:.1:2*pi;
y = sin(x);
plot(x,y)
