Python’s indexing always starts with 0, so many things need to be shifted by 1 compared to how they are in the notes or in Maple. Similarly, you can enter A.col(0) or A.col(1) or A.col(2) to extract one of the columns of A. To get the top right entry in A(which is called A WebRow Echelon Form. A matrix is in row echelon form (ref) when it satisfies the following conditions. The first non-zero element in each row, called the leading entry, is 1. Each leading entry is in a column to the right of the leading entry in the previous row. Rows with all zero elements, if any, are below rows having a non-zero element. point s levis kennedy
