此为比较奇异值分解的算法，QR分解法和分而治之法，并带入了Lapack的选择控制的接口程序，方便在matlab下实用这两种不同的算法进行比较-the algorithm about the decomposition of singular value of matrix comparing the different algorithm in the lapack QR and divide and conquer (DAC)

使用matlab，用于基于奇异值分解（SVD）的图像压缩-image compression based on Singular value decomposition (SVD)
