h1=(randn(1)+1j*randn(1));
h2=(randn(1)+1j*randn(1));
h3=(randn(1)+1j*randn(1));
z=sort(h1,h2,h3)

Error using sort

Dimension argument must be a positive integer.

在 MATLAB Online 中打开

h1=(randn(1)+1j*randn(1));
h2=(randn(1)+1j*randn(1));
h3=(randn(1)+1j*randn(1));
z=sort([h1,h2,h3])
z = 
  -0.2708 - 0.7018i  -0.9067 - 0.1721i  -1.4720 + 0.8297i

Note that by default, sort() operates along the first non-scalar dimension, so if you were to use vectors you would have to be careful about how you sorted.

h1=(randn(5,1)+1j*randn(5,1));
h2=(randn(5,1)+1j*randn(5,1));
h3=(randn(5,1)+1j*randn(5,1));
z=sort([h1,h2,h3], 2)           %sort along rows
z = 
  -0.2910 - 0.0564i   0.5709 - 0.5409i   0.6546 - 0.5143i
  -0.1828 - 1.6783i  -0.7043 - 2.3840i  -1.8560 - 1.7280i
   0.1197 - 0.5495i   0.4678 + 0.4002i   0.0720 + 1.4020i
  -0.0402 - 0.0571i  -0.0619 + 0.6243i  -1.6263 + 1.0778i
  -1.1198 + 0.7075i   0.3973 + 2.4295i   0.0284 + 2.7152i

However... you need to be clearer as to what it means to you to sort complex data. MATLAB has a meaning for sorting complex data, but it is not likely that MATLAB's meaning is the same as what you want.
