添加子文件夹路径举例
addpath('./functions');
结构体使用举例：
首先对结构体初始化，貌似matlab中不需要提前声明。
para = para_init();
function [para] = para_init()
%Construct a struct of the initial values for all the parameters
% [values] = para_init()
%Inputs:
% None
%Outputs:
% para: a struct
%Date: 14/61/2023
%Author: Zhaolin Wangpara.N = 65; % the number of transmit antennas
para.N_RF = 5; % the number of RF chains
para.T = 128; % the length of coherent time blockpara.Pt = 10^(20/10); % overall transmit power (dBm)
para.K = 4; % user number
para.noise = 10^(-60/10); % noise power in dBm
para.Rmin = 0; % minimum communication ratepara.c = 3e8; % speed of light in free space
para.f = 28e9; % carrier frequency
para.D = 0.5; % antenna aperture
para.d = para.D/(para.N-1); % antenna spacingpara.rho_0 = 1/(4*pi*para.f/para.c); % reference pathloss% location of target
para.r_s = 20;
para.theta_s = 45*pi/180;end
在使用时也只需要对结构体中的各个变量正常使用即可。
