How to pick out rows from a 2D cell array based on several criteria

I have a 2D cell array. The first column is a string, the columns 3:5 are x, y, z coordinates, and the remaining columns are data. I need to be able to pick out the rows that match a specified string and coordinates and put them into new array.
The only way I figured out how to do this is (in is the input array, name is the string I want to match, xyz are the coordinates.)
a=find(strcmp(in(:,1),name));
b=find(cell2mat(in(:,3))==x);
c=find(cell2mat(in(:,4))==y);
d=find(cell2mat(in(:,5))==z);
e=intersect(a,b);
f=intersect(c,d);
g=intersect(e,f);
out=in(g,:);
Seems pretty cumbersome, is there a better way to do this?

in={'a' [1] [2] [3] [100];'b' [11] [12] [13] [1000]}
x=1;y=2;z=3; % Your data
%-----------------------The code----------------------------------------
out=in(arrayfun(@(x) isequal(in{x,1},'a')& isequal(cell2mat(in(x,2:4)),[x y z]),[1:size(in,1)]'),:)
