same y label on both sides of contourf

From the following example:

[C,h] = contourf(peaks(20),10);
colormap autumn

How would I include the yaxis on the left hand side as well as the right hand side i.e. have the yaxis on both sides of the plot?

Here goes, plotting an extra axes in the same position, making it transparent and changing the location of the y-axis.

[C,h] = contourf(peaks(20),10);
colormap autumn
add = gca;
extra = axes('Position',get(add,'Position'),'Color','none','XTick',[],'YAxisLocation','right');
linkaxes([add extra],'xy');

The set Position is probably unnecessary.

Alternatively you can just copy the old axes and paste it over:

new = copyobj(gca,gcf);
set(new,'YAxisLocation','right');

The linkaxes() will keep the two synchronized.
