亲手所编，定点矩阵求逆，包括定点的相加、相减、相乘、相除。其中，考虑了运算过程中的Q值，精度，溢出相关问题，并且使用了大数运算，以补码形式表示大数。读者可以根据此代码根据需要进行扩展！-Made by hand, fixed-point matrix inversion, including fixed-point of the sum, subtraction, multiplication, division. Among them, taking into account in the process of computing Q values, precision, overflow-related issues, and used the lump sum for the computation in order to complement the form of large numbers. According to the code reader can be expanded as needed!相关搜索： inv_fixed
