【Abstract】 This paper generalizes the converse problems of simultaneous linear equations, discusses more general matrix equations XB=C, and gives criterion conditions under which this class of equations has symmetric matrix solutions, positive definite symmetric matrix solutions, and orthogonal matrix solutions, respectively. It also gives the structure of the solution set and the method to find the solutions. This paper solves the converse problems of simultaneous linear equations and matrix.更多还原
