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

@C.G. - since you have the file name in your files structure, then you could just do

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

thats great thank you!
