How can I change the values of the axis to use values from a vector instead of matrix position

I have a plot in imagesc where I want it to use the values of the original vector instead of the position value of the matrix, i.e. the range of the vector I used originally is 200 (-10:0.1:10) and I want to use those instead of the position 1:200. From this

Use the get and set functions to get the ticks, then relabel them:
xt = get(gca, 'XTick');
yt = get(gca, 'YTick');
xtix = linspace(-10, 10, length(xt));
ytix = linspace(-10, 10, length(yt));
set(gca, 'XTick',xt,'XTickLabel',xtix, 'YTick',yt,'YTickLabel',ytix)
This will get you started. Make necessary changes to get the result you want.
(Instead of using gca, it is better to use the actual axis handle, but this will work.)
Also, for your purposes, use:
axis equal
