The rank of a matrix A is the dimension of the vector space formed by its columns in linear algebra. In this article we will learn some useful information about this.
If the determinant of a 2 × 2 matrix is NOT 0, then its rank is 2. If its determinant is 0, then its rank is either 1 or 0. The exact rank can be found by converting it into echelon form or normal form. How to Find the Rank of a Matrix Using Determinant? To find the rank...

Rank of a matrix:The rank of a matrix specifies the dimensions, i.e. the maximum number of independent rows and or the maximum number of independent columns. If the matrix is a square matrix, the rank will be the number of either columns or rows, as both are same. But for a mXn ...
Hi guys,I've tried with the following formula to make a blank array but in vain =LET(x,MAKEARRAY(2,2,LAMBDA(r,c,"")),ISBLANK(x))So what should I return...
