数字1以“\”形对角斜线排列,其他值全部为0的矩阵为单位矩阵(Identity Matrix),记作I(或In×n)。矩阵同单位矩阵相乘时,满足交换率,所得结果为矩阵本身,即A*I = I*A = A。因此,单位矩阵也被称为恒等矩阵。逆矩阵当矩阵A*B=B*A=I时,我们称B是A的逆矩阵(Inverse Matrix),记作B=A^-1,而A则被称为...
For example, det can produce a large-magnitude determinant for a singular matrix, even though it should have a magnitude of 0. Algorithms det computes the determinant from the triangular factors obtained by Gaussian elimination with the lu function. [L,U] = lu(X) s = det(L) % This is ...
