The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
Since inupper triangular matrix, all elements under the principal diagonal are zeros, the eigenvalues are nothing but the diagonal elements of the matrix. What are the Eigenvalues of a Unitary Matrix? Aunitary matrixis a complex matrix such that its inverse is equal to its conjugate transpose. ...
Find the inverse of f(x) = 3x- 4 . What is a function's inverse? How can one find the function when the inverse function is given such as f^{-1}(x)= \frac{x+4}{2} ? How do you figure out inverse matrices? How to find the inverse of tan(x) ...

inverse这里指的是求这个3阶方阵的逆阵。具体方法就是初等变化，如果你会的话，方法如下：假设这个方阵是A，3阶的单位方阵为E，那么 A|E-->E|B。这里的B就是所求的逆阵。做法就是利用行初等变化把A变成E，同时用相同的行初等变化就把E变成了B。在理论上很好解释。这一系列的行变化就相当于B*...
In summary, we have a matrix with dimension NxN. For some m belonging to N, m0, we have A^m0=0. We consider the exponential matrix e^A=I+A+A^2/(2!)+A^2/(3!)+A^m/(m!). We need to find the inverse matrix of e^A. Using the property that if A and B commute, then ...
Let A = (2 3 1 3 3 1 2 4 1). (a) Find the inverse of the matrix (if it exists). (b) Find the determinant of the matrix. Find the determinant of the matrix if this matrix invertible? (3,1,2,-1,1,0,0.2.1) how to find inverse of a matrix quickly ...
In summary, the conversation is about finding the inverse of a given matrix A mod 26. The person is confused about the Euclidean algorithm and how to proceed with finding the inverse. Another person suggests using modulo 26 arithmetic to solve for the inverse and provides an example. The...
