Indexing, MATLAB in Statistics

Assignment Help:

Indexing:

The Indexing is an alternate to sort a vector. With indexing, the vector is left in its original order. An index vector is used to point values in the original vector in the preferred order.

For illustration, for a vector of exam grades as shown below:

In ascending order, the minimum grade is in element 2; the next minimum is in element 5, and so forth. The index vector grade_index gives this order:
