You can conjugate transpose a matrix by using the ' operator. That is
the entry in the
ith column and the
jth row will be
the complex conjugate of the entry in the
jth column and the
ith row of the original matrix.
Note that normal transpose, that is the .' operator, is much faster and will not create a new copy of the matrix in memory. The conjugate transpose does create a new copy unfortunately. It is recommended to always use the .' operator when working with real matrices and vectors.
