摘要
当方程组有惟一解时,由逆矩阵可得解;当方程组有无穷组解时,由右伪逆矩阵可得满足方程的解中最靠近原点的解;当方程组无解时,由左伪逆矩阵可得出使｜｜AX-B｜｜最小化的近似解X0。
In this article, in order to have a complete recognition about the solution to linear equation AX=B, the writer uses pseudoinverse matrix to make a further discussion about the solution to linear equation AX=B.
