To facilitate printing vectors, implement a function

that outputs the string msg, followed by the elements of x, eight per line. Place the file printvec.m in a directory of your choice, and add the directory to the MATLAB search path.

2.

Using least squares, fit a line and a parabola to the data. Plot the two curves on the same set of axes.

Compute the condition number of the associated Vandermonde matrix in each case.
