MATLAB: How to read .txt file which have complex numbers and how to separate real and imaginary parts of the complex numbers

Question

I have been trying to load .txt file which is attached with this post. Actually my task has two parts:

a) How I can read the .txt file which comprised of complex numbers?

Note:

I have been trying with textread command but it is assigning the real and imaginary part of the complex number in different rows. Actually I want both real and imaginary part of the complex number in a same cell.

b) How can I sepaarte the real and imaginary part and put them in separate columns?

Answer 1

fid = fopen("smithchartall.txt") ; 
S = textscan(fid,'%f %f %f\n','HeaderLines',1) ; 
fclose(fid) ; 
C1 = S{1} ; C2 = S{2} ; C3 = S{3} ; 
% Seperate real and imaginary 
C2_real = real(C2) ; 
C2_imainary = imag(C2) ;
