Regression Analysis Problem . [#mf54545f] †

Find the coefficients of the linear and quadratic regressions from the North Pacific mean wind speed data using the least squares method.
```
# textread or fscanf
# polyfit 
```
Extrapolate the temperature 100 years from now from the obtained regression equation and plot it together with the data.
```
# polyval
# plot, 'LineStyle', 'LineWidth'
```
Indicate the names of the x- and y-axis coordinates and the type of line in the plot. The font should be Times and the size should be 14 points (keep this format for the following questions).
```
# xlabel, ylabel, legend
# set(gca,'FontSize',14,'FontName','Times')
  -> 'gca' refers to the currently used coordinate axis
```
