Multiple column cases

Now that each operator is verified for single column vectors, all that remains is to verify proper action on multiple columns of input. To check cI()'s action on multiple columns, perform the following test at the octave prompt:

in=randn(prod(S),3)+i*randn(prod(S),3); %# Form random input with 3 columns
out1=cI(in); %# Output of new operator
out2=[cI(in(:,1)), cI(in(:,2)), cI(in(:,3))]; %# Output using debugged case
max(abs(out2-out1)) %# Check maximum value for discrepancy in each column

Finally, you should repeat the test, substituting each of the remaining operators for cI in the code fragment above.
