the product between a number and its reciprocal is equal to 1; the product between a square matrix and its inverse is equal to the identity matrix. Definition Let us start with a definition of inverse. DefinitionLet be a matrix. Its inverse, if it exists, is the matrix that satisfies whe...
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., \({\left( {{A^{ – 1}}} \right)^T} = {\left( {{A^T}} \right)^{ – 1}}.\). If \(A\) and \(B\) are square non-singular ...
也就是说,实对称矩阵是埃尔米特矩阵的特例。 https://en.wikipedia.org/wiki/Hermitian_matrix In mathematics, aHermitian matrix(orself-adjoint matrix) is acomplexsquare matrixthat is equal to its ownconjugate transpose—that is, the element in thei-th row andj-th column is equal to thecomplex ...
PerspectiveMatrix[3][3] =static_cast<T>(1);// 正常情况下, PerspectiveMatrix的行列式应该不为0if(epsilonEqual(determinant(PerspectiveMatrix),static_cast<T>(0),epsilon<T>()))returnfalse;// 判断最后一行是否为(0, 0, 0, 1), 如果不是, 则提取出Projection Matrix// 这里看似是判断矩阵最后一列,...

An orthogonal matrix is defined as a matrix whose inverse is equal to its transpose. It is characterized by having orthogonal columns of unit length, making it a key concept in linear algebra and matrix operations.
