MATLAB: How to extract corresponding values of x-axis based y-axis values.

Question

Good day,

Could someone please help me on how to extract corresponding values of x-axis based on y-axis values?

x=[1,3,4,8,3,5,6,4,5,6,7,9]

y=[3,5,6,7,4,5,6,7,8,0,3,4]

I would like to extract the corresponding values of these elements; 5,6,7,4,5,6,7(values from y-axis) in x-axis.

I only know how to find a corresponding single value not multiple values.

Thanks

[z, zIdx] = mink(y,7); 
xz = x(zIdx);
