Hi all,
I am using the below code to plot the figures of interst. I want to have Greek character with subscript in the tile of figures. For example:
μw(w is subscript)=10%
σw(w is subscript)=5%
μγ(γ is superscript)=100 lb/ft^3(pound per qubic feet)
clear
close all
clc
load('POFDE.mat');
data = cell2mat(POFDE);
[lat,lon] = meshgrid(unique(data(:,1)),unique(data(:,2)));
for i = 1:(size(data, 2)-2)
figure
I = scatteredInterpolant(data(:,[1 2]), data(:,i+2));
contourf(lon,lat,min(1,max(0,I(lat,lon))),'ShowText','on')
colorbar
title(sprintf('The probability of frost depth exceedance of %d feet', i))
exportgraphics(gca, sprintf('FrostPlot_%d_feet.png', i))
end

Here is how you can add subscripts with Greek letters:
load('POFDE.mat');
data = cell2mat(POFDE);
[lat,lon] = meshgrid(unique(data(:,1)),unique(data(:,2)));
for i = 1:(size(data, 2)-2)
figure
I = scatteredInterpolant(data(:,[1 2]), data(:,i+2));
contourf(lon,lat,min(1,max(0,I(lat,lon))),'ShowText','on')
colorbar
title(['The probability of frost depth exceedance of \Omega_{\delta} = ' num2str(i) ' feet'])
exportgraphics(gca, sprintf('FrostPlot_%d_feet.png', i))
end

t = sprintf('\\mu_w = %.1g%%'), muw_percentage);
title(t, 'Interpreter', 'latex')

An alternative way is:
load('POFDE.mat');
data = cell2mat(POFDE);
[lat,lon] = meshgrid(unique(data(:,1)),unique(data(:,2)));
for i = 1:(size(data, 2)-2)
figure
I = scatteredInterpolant(data(:,[1 2]), data(:,i+2));
contourf(lon,lat,min(1,max(0,I(lat,lon))),'ShowText','on')
colorbar
title(['The probability of frost depth exceedance of $\Omega_{\delta}$ = ' num2str(i) ' feet'], 'Interpreter', 'Latex')
exportgraphics(gca, strcat(['FrostPlot_', num2str(i) '_feet.png']))
end
