WebAll rows consisting entirely of zeros are at the bottom. In each row, the first non-zero entry form the left is a 1, called the leading 1. The leading 1 in each row is to the right of all leading 1’s in the rows above it. If, in addition, each leading 1 is the only non-zero entry in its column, then the matrix is in reduced row-echelon form. WebApr 9, 2024 · Use the correct data types. Explore your data.
