WebMar 24, 2024 · Pivoting. The element in the diagonal of a matrix by which other elements are divided in an algorithm such as Gauss-Jordan elimination is called the pivot element. … WebThe second pivot is the (2,2) entry of this matrix, which is 2, and is the coeﬃcient of the second variable in the second equation. Again, the pivot must be nonzero. We use the elementary row operation of adding 1 2 of the second row to the third row to make the entry below the second pivot equal to 0; the result is the augmented matrix N = 1 2 1 chiranjeevi mp3 songs download telugu
