Remove Terms in Complex Valued Data That Has Only Real or Imaginary Part
Mostrar comentarios más antiguos
I have a complex numeric array (file attached) that some of its terms have only real or imaginary part, and the rest have both the real and imaginary part. How can I remove the terms in the array that has only one term (real or imaginary) so that the terms that has both real and imaginary are left in the array? For example, for the first 8 rows of the data, I want to remove the first 7 terms:
0.000 + 0.254i
0.000 + 0.317i
0.000 + 0.298i
-0.0467 + 0.000i
0.000 + 0.317i
0.000 + 0.401i
0.000 + 0.437i
-0.0453 + 0.0029i % only this term is needed
Thank you!

load LR
disp(LR);
One way:
% remove elements of LR whose real part is 0 or imaginary part is 0
LR(real(LR) == 0 | imag(LR) == 0) = [];
disp(LR);
Another way:
load LR
% keep elements of LR whose real part is non-zero and imaginary part is non-zero
LR = LR(real(LR) ~= 0 & imag(LR) ~= 0);
disp(LR)
load LR
% same but more concise:
LR = LR(real(LR) & imag(LR));
disp(LR)
