Delete row with same value but in different columns

I have a matrix like:

[1	1	2	1	47 ; 1	  1	47	1	2]

How to delete one of the rows and keep the other ?

Thanks

For example, to delete the first row,

A=[1	1	2	1	47 ; 1	  1	47	1	2]

A = 2×5

1 1 2 1 47 1 1 47 1 2

A(1,:)=[]

A = 1×5

1 1 47 1 2

I have more than only two rows lol. I need to delete all but one.

unique(sort(angles_new,2),'rows');

This works but i do not want to sort my values since i need to keep the 3rd column element where it is.

[~,idx] = unique(sort(angles_new,2),'rows');

angles_new=angles_new(idx,:); %unsorted
