Specify a matrix

To use the specific matrix

$$\begin{pmatrix}c_{0~0}& c_{0~1}& &\ldots& &c_{0~2^n-1}\\ c_{1~0}&... ...& &\ldots& & \\ c_{2^n-1~0}&c_{2^n-1~1}&&\ldots& &c_{2^n-1~2^n-1} \end{pmatrix}$$ (6)

as the initial state, command ``init-mixed'' with a subsequent matrix:

init-mixed ( $c_{0~0}~~c_{0~1}~~\ldots~~c_{0~2^n-1}$)( $c_{1~0}~~\ldots~~$) ... ( $c_{2^n-1~0}~~c_{2^n-1~1}~~\ldots~~c_{2^n-1~2^n-1}$);

$c_i$ may be written in the style of ``0.2+0.3i'' or ``0.4ej0.25pi''. We recommend ``mload'' command rather than this invocation.
