// This file implements the Xsymm routine. It is based on the generalized matrix multiplication
// routine (Xgemm). The Xsymm class inherits from the templated class Xgemm, allowing it to call the
// "DoGemm" function directly. The "DoSymm" function first preprocesses the symmetric matrix by
// transforming it into a general matrix, and then calls the regular GEMM code.
