MATLAB: Logical Indexing with Complex Numbers

The only approach I can suggest is:

A = rand(5) + 1j*(rand(5)*eps + rand(5).*(rand(5)>0.5));    % Create ‘A’
Ar = real(A);
Ai = imag(A);
ix = Ai<=eps;
Ai(ix) = 0;
Anew = Ar + 1j*Ai;

The problem with dealing with logical indices is that it can be difficult to retain the matrix orientation. Logical references can result in creating column vectors from matrices, frequently not the desired outcome. This approach avoids that, at the expense of a bit of inefficiency in creating separate real and imaginary component matrices of ‘A’.

MATLAB: Double precision changes to complex double after calculation

Theory one: You use i as a variable. As this is a "reserved word" for complex calculations, there may be an unexpected effect.

Theory two: One of your functions or variables shadows the real MATLAB command and does something unexpected. Like you would assign plot=1 the then try to use the plot command.
