I want to adjust the postion of the text S0=(1,1,0,0) and to put each in fron of a,b and c in the subplots. I also want to redue the space between the subplots denoted 1 and 2 enclosed by red rectangles. How can I do it? My program and figure can be seen:
clc;
clear all;
close all;
%% ------------------------------Program-------------------------------------
N0=100;
r_med=[0.445 0.889 1.445 2];
sigma_g=7;
N_ang=9001;
theta=0:0.01:180;
col=['k' 'b' 'r' 'g'];
for i=1:length(r_med)
[P11(i,:),P12(i,:),P33(i,:),P34(i,:),~,~,~] = ZK_W_Cloud_PhaseFunc(N0,r_med(i),sigma_g,N_ang)
f1(i,:)=((P11(i,:)-P12(i,:))./2);
f2(i,:)=((P11(i,:)+P12(i,:))./2);
f3(i,:)=P33(i,:)/2;
%numer(i,:)=0.125*((f2(i,:).*(cosd(theta)).^2)+f1(i,:)-(2.*(f3(i,:).*cosd(theta))));
denomin(i,:)=0.125*((3.*(f2(i,:).*(cosd(theta)).^2))+(3.*f1(i,:))+(2.*(f3(i,:).*cosd(theta))));
%ldpr(i,:)=smooth((numer(i,:)./denomin(i,:)));%Linear depolarization ratio

Try using the text command, which lets you specify location.
For your subplot spacing, try using tilelayout instead. It has optional inputs for TileSpacing and Padding.
t = tiledlayout(1,3,'TileSpacing','Compact','Padding','Compact');
