C++实现矩阵的SVD分解，矩阵基本运算“+，-，*，/”，三角分解，QR分解，矩阵显示，矩阵转置，矩阵特征值与特征向量运算.
并在 Source.cpp中附有使用例子代码，方便读者快速上手。
经本人测试，完全可以运行，放心使用。
对于SVD分解，经过与matlab中结果对比，发现，当矩阵的列数>=行数时，基本没问题。(Using C++ language　realizes the SVD decomposition of matrix,as well as the basic operation of matrix "+, -, *, /", triangular decomposition, QR decomposition, matrix display, matrix transpose, matrix eigen value and eigen vector operation.
And in Source.cpp, how to use these code was supplied, which is very convenient for you to quickly use these codes into your programming.

For SVD decomposition, I had　compare the result　with that of MATLAB,and I found that when the columns of the matrix number > = line number,my code has no problem.)
