Pure JavaScript game engine. Fully featured and production ready.

/**
 * Applies a Givens rotation (c, s) to two row vectors in place:
 *
 *     row_i' =  c * row_i + s * row_j
 *     row_j' = -s * row_i + c * row_j
 *
 * Each row is treated as a length-n vector and rotated element-by-element.
 *
 * Accepts plain arrays or typed arrays. The two row arguments can be
 * standalone arrays or subarray views into a larger flat matrix — useful
 * for row-major QR/Hessenberg maintenance where the matrix is a single
 * Float64Array and the caller hands in `M.subarray(i*n, (i+1)*n)` and
 * `M.subarray(j*n, (j+1)*n)`.
 *
 * @param {Float64Array|number[]} row_i length >= n
 * @param {Float64Array|number[]} row_j length >= n
 * @param {number} c
 * @param {number} s
 * @param {number} n number of elements to rotate
