Find which row of 3d matrix matches an array along the third dimension. For ex:![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/623298/image.png)

I want to find [1 0 0] along 3rd dimension of Zb, so here Zb(4,1,:) , Zb(5,4,:) and some others match [1, 0, 0]. How to know if the match occurs (for any random value of 3rd dimension of matrix) and if so, what are the row, column indices? Also, can this be done without for loop?

you can use e.g.
a(:,:,1)=ones(2);
a(:,:,2)=2*ones(2);
a(:,:,3)=[1 3; 3 1];
pattern(1,1,:)=1:3;
whereToFind=all(a==pattern,3)
