pivotelementistä
A pivot element is a fundamental concept in various algorithms, particularly in numerical linear algebra and data structures. In the context of algorithms like Gaussian elimination or quicksort, a pivot element is a chosen element in a matrix or an array that is used to simplify the remaining parts of the structure.
For example, in Gaussian elimination, a pivot element is typically a non-zero entry on the diagonal of
In the quicksort sorting algorithm, the pivot element is an element chosen from the array. The array
