  "Description": "Pairwise Hamming distances are computed between the rows\nof a binary (0/1) matrix using highly optimized 'C' code. The\ninput is an integer matrix where each row represents a binary\nfeature vector and returns a symmetric integer matrix of\npairwise distances. Internally, rows are bit-packed into 64-bit\nwords for fast XOR-based comparisons, with hardware-accelerated\npopcount operations to count differences. 'OpenMP'\nparallelization ensures efficient performance for large\nmatrices.",
