It depends what you want exactly.
Let's say you have two vectors a and b:
a=[1;2;3;4];
b=[0;2;3;5];
To find the indices where a equals to b, you can simply compute:
a == b
ans =
4×1 logical array
0
1
1
0
To get the values and the indices where a equals to b, you can also have a look at the find function.

Thanks for community support. let me phrase my questions with more detail
lets suppose i have vertices of a tea cup.
Vx =[ 0;1;2;0;9]
Vy = [1;1;,2;;3]
Vz= = [38,32,-1]
They are cancatenated in a larger matrix = [Vx Vy Vz].
After sorting, i want to find first elements or coordinates like (0,1,38) here in Vx,Vy,Vz wherever they meet or match, it should be labelled as 5 in that particular grid.
Your guidance will be highly appreciated.
regards
