A)

yplot=y;              % make a copy of the data specifically for plotting
yplot(yplot==0)=nan;  % replace 0 elements with NaN
plot(x,yplot)

will return broken lines between locations which contain zero in yplot

B)

isNZ=(~y==0);           % addressing logical array of nonzero elements
plot(x(isNZ),y(isNZ))   % plot only the subset

will be solid line just without those points that were zero
