For example:
X=[1;2;3;4;5];
Y=[2];
if this matched than i should get Z as matched value like this
Z=[2];

I don’t understand what you are doing or what ‘matched’ means.
It would seem that the intersect function might be what you want:
Z = intersect(X,Y)
that would produce:
Z =
2

It may not work with floating point numbers if the numbers were arrived at in different ways. See http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F

True.
In that event, it would be necessary to use the R2014b version of round on both, or equivalently:
roundn = @(x,n) fix(x.*10.^n)./10.^n;
wnere x is the number (or matrix) to be rounded, and n the number of digits to be rounded to.

Another way may be:
X=[1;2;3;4;5];
Y=[2];
Z = X(X==Y)
