线性代数:转置矩阵(matrix transpose)和逆矩阵(matrix inverse) 都是直接的仿射空间变换,就是仿射空间A变换到仿射空间B,使用矩阵也都是如下: 矩阵T*齐次坐标V = 齐次坐标V' 其计算细节也就是矩阵行与向量列的点积,其计算意义也就是获得新仿射空间中的坐标分量,也聊了很多了。 这次我们就来学两个矩阵的操作,...

This map is going to be reflecting about y=x line so they should have eigenvalues 1 and -1 respectively! Since the transpose matrix A is also equal to the inverse matrix A (because it is an orthogonal matrix from the given info) Upvote • 1 Downvote Comments • 2 John D. ...
If determinant is zero, an inverse of the matrix does not exist. For example, if an entire row or column of a matrix is zero or if two rows or columns are equal, the determinant is zero. Determinant is also used to solve a series of equations. Only a square matrix, like the Matrix...

If a square matrix \(A\) has an inverse, then the transpose of an inverse matrix is equal to the inverse of the transposed matrix. i.e., \({\left( {{A^{ – 1}}} \right)^T} = {\left( {{A^T}} \right)^{ – 1}}.\). ...
