Matlab redundancies in a two column vector

[JCienfuegos]

Hello
I am new to MATLAB and I am trying to perform the task of removing redundancies from a two column vector.
One column holds the indices, the other column holds the values. I don't know how to remove the redundant values!
Any ideas? I have hear that Unique works, but I have the feeling it is for arrays which are not indexed.
I tried using a loop that checked every element currently in the array before allowing another value to be added, but the loop wound up going on forever. So far, the loop has been running for about 20 minutes.

You can use the 'unique' function in MATLAB to remove redundant values from a two-column vector. It works by comparing the values in each column and eliminating any duplicates.To do this, you first need to specify the data type of the values in the vector. For example, if the values are integers, you can use the 'int8' or 'int16' command. Once the data type is specified, you can call the 'unique' function as follows: [~,IA,IC] = unique(vector,'rows','stable');The output IA contains the indices of the unique elements in the original vector, while IC contains the indices of the first occurrences of each unique value. You can then use this information to construct a new vector with only the unique elements from the original vector. For example, to construct a new vector called 'new_vector' with only the unique elements from the original vector, you can use the following syntax: new_vector = vector(IA,:);This will create a new vector which contains only the unique elements from the original vector.
