I need to map a binary array to 2 differnet values corresponding to 0 & 1

A= zeros(320,320); A(60:180,60:180)=1;

lets say I wanna make all 1's = 2+3i and all 0's equals to 8-4i.

What would be the syntax to map them to corresponding values. Thanks

One of a zillion ways...

C=complex(2*ones(size(A)),3*ones(size(A)));
C(C==0) = 8-4i;

Another less "deadahead" but one-liner...

C=interp1([0 1],[8-4i 2+3i],A,'nearest');

ADDENDUM

A variation on the latter is simple lookup...requires the temporary vector, though.

v=[8-4i 2+3i];           % the values
C=v(A+1);                % convert logical to array indices
