Block circulant matrix
分組循環矩陣The characteristics of different parallel algorithms are compared in accordance with the specialty of coefficient matrix of vibration equations of wheel / rail system. then, four parallel algorithms are used to solve the linear equations, such as gaussian elimination, lu decomposition, ldr decomposition and wz decomposition. with the method of cyclic distribution, all rows of the coefficient matrix is allotted into different processes, then eliminated and decomposed by relevant processors
針對輪軌系統振動方程組系數矩陣的特點,分析了現有各種求解線性方程組并行演算法的優缺點,選擇高斯消去法、 lu分解、 ldr分解和wz分解法作比較,採用循環帶狀劃分的方法將系數矩陣的各行分配到各進程,由各個處理器完成所分配矩陣行的消元和分解。
