+* Computes the Schur factorization of a real 2-by-2 nonsymmetric matrix `A` in standard form.
+*
+* Given a real 2×2 matrix:
+*
+* ```tex
+* \begin{bmatrix}
+* A & B \\
+* C & D
+* \end{bmatrix}
+* ```
+*
+* this routine computes an orthogonal matrix:

+* ```tex
+* \begin{bmatrix}
+* \text{CS} & \text{SN} \\
+* -\text{SN} & \text{CS}
+* \end{bmatrix}
+* ```
+*
+* such that the matrix is reduced to Schur (quasi-triangular) form:
+*
+* ```tex
+* \begin{bmatrix}
+* \text{AA} & \text{BB} \\
+* 0 & \text{DD}
+* \end{bmatrix}
