saving figure with title as name of file

I have 4 .mat files. I extract the data from these, plot them and save each figure.
Now, I want the title of the plot, and the name of the png file i save to be the name of the .mat file the data is from.
How do I go about doing this?
files = dir('*.mat');
num_files = length(files);
resGT = zeros(100000,num_files);
%calculate resGT
for a = 1:num_files
load(files(a).name)
v = vel(1:100000,:);
e = num;
timestep = height(vel);
time_sec = timestep/100;
inputrate = 1;
resGT(:,a) = sqrt(v(:,1).^2 +v(:,2).^2 + v(:,3).^2);
end
%plot
for a = 1:num_files
figure()
cla;
plot(resGT(:,a)) %GT over time
title ('GT through time')
xlabel('Time')
ylabel('GT')
saveas(gcf,sprintf('ResGT%d.png',a))
hold on
pause(0.5)
end

for a = 1:num_files
matFileName = files(a).name;
figure()
cla;
plot(resGT(:,a)) %GT over time
title (matFileName)
xlabel('Time')
ylabel('GT')
saveas(gcf,sprintf('%s.png',matFileName))
hold on
pause(0.5)
end
