%You can use this function by passing your species_t cell array as an argument. The function will return the indices of the similar values in each pair of cell arrays as a cell array repeatedIndices, where repeatedIndices{i,j} represents the indices of the similar values between species_t{1,i} and species_t{1,j}.
