NumPylinalg.inv()function in Python is used to compute the (multiplicative) inverse of a matrix. The inverse of a matrix is that matrix which when multiplied with the original matrix, results in an identity matrix. In this article, I will explain how to use the NumPy inverse matrix to com...
error: matrix multiplication: inverse of singular matrix; suggest to use solve() instead singular matrix为奇异矩阵 【设A为n阶方阵,若存在另一n阶方阵B,使得AB=BA=I,则称A为非奇异矩阵,若不存在,则为奇异矩阵。 当exogenous variable 中虚拟变量过多,可能产生singu... ...
