find element of a cell or char array that matches a nonleading substring

This question seems closely related to thread 50624-testing-for-the-presence-of-a-substring-in-a-cell-array-of-strings but has an extra wrinkle.
I have an array of the form x = {'010','030',...,'310'} and a string y = 'W_030_000'. I'd like to find the element of x which matches some portion of the string y. In this example, the second element of x is the one I want to find. Obviously, I could do this if I restricted to y(3:5), then I could use strmatch, but I'd rather not have to be that explicit.
Thanks for any advice!

x = {'010','030','310'}
y = 'W_030_000'
out=x( ismember(x,regexp(y,'\d+','match')))

An alternative:
x = {'010','030','310'};
y = 'W_030_000';
ys = strsplit(y,'_');
[Q,ia,ib] = intersect(x,ys);
