I have a push button in gui which calculates the different stresses of each layer in a composite laminate. How can I transfer each of these values obtained into another push button, to test failure in each layer. Note: Values are not const (Looped)

for f=1:length(theta3)

m=cosd(theta3(f));

n=sind(theta3(f));

alfax=(m^2.*alpha1(f))+(n^2.*alpha2(f));

alfay=(n.^2.*alpha1(f))+(m.^2.*alpha2(f));

alfaxy=(2.*m.*n).*(alpha1(f)-alpha2(f));

alphaa=[alfax;alfay;alfaxy]

stress_top{f}=(Qba{f}*(ep_top{f}-alphaa*deltat))*1000;

stress_bottom{f}=(Qba{f}*(ep_bottom{f}-alphaa*deltat))*1000 ;

stress_topX(f)=stress_top{f}(1);

stress_topY(f)=stress_top{f}(2);

stress_topXY(f)=stress_top{f}(3);

stress_bottomX(f)=stress_bottom{f}(1);

stress_bottomY(f)=stress_bottom{f}(2);

stress_bottomXY(f)=stress_bottom{f}(3);

end
