suppose you have a 1x3001 complex matrix that are the roots of a function, find the roots with zero real part. in matlab

main.m
% Generate a 1x3001 random complex matrix
complexMatrix = rand(1, 3001) + 1i*rand(1, 3001);

% Find the roots with zero real part
rootsWithZeroRealPart = complexMatrix(imag(complexMatrix) ~= 0);

disp(rootsWithZeroRealPart);
