换句话说,不可逆的情况是少见的,所以不可逆矩阵就称为Singular matrix,这里的singular就是special, not common的意思啊。同理,可逆矩阵很常见,所以就是非奇异矩阵了。 举个例子就更好明白了,现假设一个 (1×1) 的矩阵,我们知道只有这个矩阵等于0的时候才是不可逆的,其余情况都是可逆的;再看 (2×2) 的矩阵...
If you take an n×n matrix "at random" (you have to make this very precise, but it can be done sensibly), then it will almost certainly be invertible. That is, the generic case is that of an invertible matrix, the special case is that of a matrix that is not invertible. For exa...
主要说了个什么事呢,意思就是假设随机生成一个\(n×n\)的矩阵,绝大多数情况这个矩阵都是可逆的,也可以理解为它的行列式不为0。换句话说,不可逆的情况是少见的,所以不可逆矩阵就称为Singular matrix,这里的singular就是special, not common的意思啊。同理,可逆矩阵很常见,所以就是非奇异矩阵了。 举个例子就更...
If A is a square matrix, and if the determinant of A equals zero (i.e., |A| = 0), then the matrix A is called a singular matrix. On the other hand, if |A| exists, the matrix A is called a nonsingular matrix. For example, the matrix A is A=[2142] is a singular matrix...
In this note, we describe a property of a special full 5×5 ray-nonsingular matrix, if such matrix exists, using the concept of an isolated set of transversals and we obtain a necessary condition for a complex matrix A to be ray-nonsingular. Moreover we give an example of a full 5...
