A matrix that has no inverse is singular. A square matrix is singular only when its determinant is exactly zero. Tips It is seldom necessary to form the explicit inverse of a matrix. A frequent misuse ofinvarises when solving the system of linear equationsAx=b. One way to solve the equat...
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...
find uses the convention that k is an empty matrix [] when X is an empty matrix []. You can return the nonzero values in X using X(k). row— Row subscripts vector Row subscripts, returned as a vector. Together, row and col specify the X(row,col) subscripts corresponding to the ...
