%% Applying Operators
% Spot operators can be multiplied by vectors just like MATLAB matrices.
% Make a vector x and apply C to it:

x = [1;2];
y = C*x

%%
% We can also multiply by the adjoint of an operator:

w = [1;2;3];
z = C'*w;

%% Subset Assignment and Reference
% If we are only interested in applying part of an operator, we can create
