Finding Duplicates in MATLAB Array
To find duplicates in a MATLAB array, you can use the unique
function along with the diff
function to identify the indices of the duplicate elements. Here's a code snippet to achieve this:
A = [1 2 2 3 4 4 4 5];
[~, idx] = unique(A);
duplicate_indices = setdiff(1:numel(A), idx);
duplicate_values = A(duplicate_indices);
This code snippet first finds the unique elements in the array A
and then identifies the indices of the duplicate elements. The variable duplicate_values
will contain the actual duplicate values in the array.
