Matlab saving figure with file name containing variables

I have no idea how to save file when the name contains variables.

A = figure();

% some code

fileName = sprintf('sig1=%d mu1 =%d p1=%.2f sig2 = %d mu2 = %d p2 = %.2f', ...
                     sigma1, mi1, double(p1), sigma2, mi2, double(p2));

print(A, fileName, '-dpng');

I got this to work:

A = figure;
plot(1:10,sin(pi*(1:10)./4))

fileName = sprintf('sig1=%d mu1 =%d p1=%.2f sig2 = %d mu2 = %d p2 = %.2f.png', ...
                     1, 2, double(3), 4, 5, double(6));

print(A, fileName, '-dpng');

The png file opened just fine. When you want the png file name to have variables in it, this is the correct approach. You can set a lot more figure specifications by using the figure handle ("A", in this case) and the set(A,...) function. Look at the matlab documentation for using the set(A,...) function and gcf. If you type get(A), you will see a list of properties that you can set before you save your figure.

Please let me know if this helps.
