All zero matrix
WebIdentity Matrix: It is a square matrix and has ones as its diagonal elements, and all the other elements are zeros. Scalar Matrix: A square matrix having the same number as all its diagonal elements and all the other elements are equal to zero. Symmetric Matrix: A matrix whose transpose is equal to the given matrix is called a symmetric matrix. Web1. This question already has answers here: Prove that if for every x ∈ R N A x = B x then A = B [duplicate] (5 answers) Closed 7 years ago. If A is a m x n matrix such that: A x = 0, for every x ∈ R n, then A = 0 is the zero matrix. I have no idea how to begin proving this. The only hint is to consider a j column in the Identity matrix I n ...

WebIf the matrix has more rows than columns, a row of all zeros does not imply a free variable. For example: $$ \left[\matrix{1 & 2\cr 3 & 4\cr 0 & 0\cr}\right]$$ One way you find free variables is: put the matrix into row-echelon form, then any column that does not contain the first nonzero entry of any row corresponds to a free variable. In your ...
WebSince the null matrix has all zeros as its elements, the null matrix is also referred to as a zero matrix. The null matrix is the additive identity of any matrix. The order of a null matrix is m x n, and it can have an unequal number of rows and columns. A few examples of zero matrix or null matrix is as follows.
