MATLAB plot with sorted order

I have two vectors in MATLAB, say:

x = [1 20 3 7 10]

and 

y = [2 51 1 9 18]

How can I plot y vs K where x has sorted value order (1 3 7 10 20) with their respective y values like the following?

x = [1 3 7 10 20]
y = [2 1 9 18 51]

XY = sortrows([x ; y]');

plot(XY(:,1), XY(:,2));

Concatenate the matrices, transpose them and then you can use sortrows to order by X

Call sort with a second output argument.

x = [1 20 3 7 10]  
y = [2 51 1 9 18]  

[xsorted, I] = sort(x)
ysorted = y(I)
