Variables i and j each have associated values. Swap them, so that i becomes associated with j's original value, and j becomes associated with is original value. You can use two more variables itemp and jtemp.

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
