My code below seems to generate and save the "figure" file. However, when I want to save this to a *.png file I tend to get an error.
How can I save a *.fig file and also generate and save a *.png file? I think I am doing something wrong with the code.
Any help is appreciated.
plot1 = plot(freq,magB_0_AOR00,freq,magB_0_AOR45,freq,magB_0_AOR90,...
title('Data Investigation');
subtitle('A=PT0, B=PT1, C=PT2')
xlabel('Frequency (GHz)');

According to the documentation for saveas, you should be able to do
If that doesn't work, then you could upload your data here, for us to test.

Here are two different ways how you can save the plot figure output in .png:
F = @(t)exp(sin(2*t));
fplot(F, [-pi, pi])
grid on
% using saveas
OUT_File_Name = 'MY_plot';
saveas(gcf, OUT_File_Name, 'png')
% using exportgraphics()
OUT_File_Name2 = 'MY_plot2.png';
exportgraphics(gca, OUT_File_Name2)
