Matlab - Find points in vicinity

Lets say I have a dataset like below.

X = [170,85; 165,75; 180,100; 190,120; 160,80; 170,70];

a distance vector

Y = [10,20];

a data point

Z = [166,77];

I want to find all the points of X that fall within the distance Y from the point Z

Answer should be ans = [170,85; 165,75; 160,80; 170,70]

How can I do this in Matlab

a= X(abs(X(:,1)-Z(1))<=Y(1) & abs(X(:,2)-Z(2))<=Y(2),:)

EDIT

Multidimensional solution can look like this:

a= X(all(abs(X-ones(size(X,1),1)*Z) <= ones(size(X,1),1)*Y,2),:)
