Problem $9\mathrm{.}5$

The following data were collected for the steady flow of water in a concrete circular pipe.

Use multiple linear regression to fit the following model to this data:

Q$=\backslash$alpha $\_(0)$D$^(\backslash$alpha $1)$S$^(\backslash$alpha $2)$

where Q$=$ flow, D$=$ diameter, and S$=$ slope.

Solve this problems writing a generalized user$-$define function that performs multi$-$variable

regression for any number of independent variables. in matlab
