How to calculate rank of matrix
WebA = ( 1 2 3 0 5 4 0 10 2) Now several sites included that info so it must be true: If, we are looking at this example, there is no line with zeroes only, the rank of this matrix will be 3. (?) Here is the problem. It will cost time to form this matrix to see if there will be lines with zeroes only. For this I can use Gaussian Elimination. Web26 jul. 2016 · 1) To find the rank, simply put the Matrix in REF or RREF [ 0 0 0 0 0 0.5 − 0.5 0 0 − 0.5 0.5 0] R R E F [ 0 0 0 0 0 0.5 − 0.5 0 0 0 0 0] Seeing that we only have one leading variable we can now say that the rank is 1. 2) To find nullity of the matrix simply subtract the rank of our Matrix from the total number of columns. So: Null (A)=3 - 1=2

Webto obtain the row echelon form (in agreement with the OP's work). It doesn't really make sense to talk about consistency here; it's just a matrix, not a system of equations. We've shown that the row echelon form has 3 leading 1 's and thus the matrix has rank 3, and thus the Rank-Nullity Theorem implies it has nullity 1. Share Cite
