multiplotyyy

MULTIPLOTYYY plots using three sets of y-axes values. Additionally, multiple lines can be plotted against each y-axis. Therefore, the inputs to the function must be grouped into cell arrays.
Here is an example call to the function:
x1 = (0:0.01:1)';
x2 = (0:0.1:1)';
x3 = (0:0.05:1)';
y1 = x1;
y2 = x2.^2;
y3 = x3.^3;
y4 = sin(x1);
y5 = fliplr(2*x1.^2);
y6 = 7*cos(x1);
y7 = 7*log(x1+1.2);
ylabels{1}='First y-label';
ylabels{2}='Second y-label';
ylabels{3}='Third y-label';
[ax,hlines] = multiplotyyy({x1,y1,x2,y2,x3,y3,x1,y4},{x1,y5},{x1,[y6,y7]},ylabels);legend(cat(1,hlines{:}),'a','b','c','d','e','f','g','location','w')
