How to omit white spaces in non standard size matlab figure?

I am using matlab R2017a version where I want to plot non standard size two figures in a particular way (see attached code). the problem is when I try to save the image in eps or pdf format then white spaces appear. please suggest a way in which I can generate non standard size plot with no white spaces for research purpose?

x = linspace(-2*pi,2*pi);

y = linspace(0,4*pi);

[X,Y] = meshgrid(x,y);

Z = sin(X)+cos(Y);

Z1=sin(X)+cos(Y);

h = axes('Position',[0.15,0.15,0.49,0.25]);

contour(h,X,Y,Z)

h = axes('Position',[0.73,0.15,0.25,0.25]);

contour(h,X,Y,Z1)

print(1,'-dpdf','filename.pdf');
