I have the following Matlab code that gives me four figures.

close all;
clear variables;
clc;
% % For Phi/Psi = +/-10
CoverageArea_mean_10 = {[84.4735,21.1779,6.4247,2.1416],[45.2112,8.8043,1.1898,0]};
CoverageArea_min_10 = {[98.5128,21.1779,6.9007,2.1416],[58.7745,10.7079,2.1416,0]};
CoverageArea_max_10 = {[70.1963,19.0363,5.9488,2.1416],[38.5485,8.3284,0,0]};
% For Phi/Psi = +/-40
CoverageArea_mean_40 = {[0,4.5211,2.3795,0],[0,0,0,0]}; 
CoverageArea_min_40 = {[92.5640,21.1779,6.9007,2.1416],[53.7775,10.4700,1.4277,0]}; 
CoverageArea_max_40 = {[0,0.4759,0.2380,0],[0,0,0,0]}; 
for i=1:2
x = [15,30,45,60];
    figure
        % For Phi/Psi = +/-10
        COVERAGE = [CoverageArea_min_10{i};CoverageArea_mean_10{i};CoverageArea_max_10{i}];
        COVERAGEAREA = [COVERAGE(:,1)';COVERAGE(:,2)';COVERAGE(:,3)';COVERAGE(:,4)'];
        bar(x,COVERAGEAREA);
        title({ 'The coverage area' ;[ '\phi = \pm10' , '\psi = \pm10' , 'FEC = 3.8\times10^{-3}' ]});
        
        xlabel( 'Semi-angle at half power, \Phi_1_/_2 (°)' );
        ylabel( 'Coverage area (m²)' );
        BarNames = { 'min' , 'mean' , 'max' };
        legend(BarNames, 'Location' , 'best' );
        grid on ;
        
        figure
        % For Phi/Psi = +/-40
        COVERAGE1 = [CoverageArea_min_40{i};CoverageArea_mean_40{i};CoverageArea_max_40{i}];
        COVERAGEAREA1 = [COVERAGE1(:,1)';COVERAGE1(:,2)';COVERAGE1(:,3)';COVERAGE1(:,4)'];
        bar(x,COVERAGEAREA1);
        title({ 'The coverage area' ;[ '\phi = \pm40' , '\psi = \pm40' , 'FEC = 3.8\times10^{-3}' ]});
        xlabel( 'Semi-angle at half power, \Phi_1_/_2 (°)' );
        ylabel( 'Coverage area (m²)' );
        BarNames = { 'min' , 'mean' , 'max' };
        legend(BarNames, 'Location' , 'best' );
        grid on ;
end

The problem is all four figures will have the same title. In the above code, each iteration gives me 2 figures. So I need to change the title of every two figures at each new iteration:

Therefore, for the first iteration, I need the following title

title({ 'The coverage area' ;[ '\phi = \pm10' , '\psi = \pm10' , 'FEC = 3.8\times10^{-3}' ]});

For the second iteration, I need the following title

title({ 'The coverage area' ;[ '\phi = \pm10' , '\psi = \pm10' , 'FEC =10^{-5}' ]});
