CAN I GET A SOLUTION IN MATLAB PLEASE. With 11 data

CAN I GET A SOLUTION IN MATLAB PLEASE.

With 11 data points given by the column vectors xdat and ydat in MATLAB, the commands u=A\ydat produce the output u=3.1505.40673.88102.4 The matrix A is of size mn, where m=n= What do the commands compute? Least squares approximation y(x)=3.150+5.406x73.88x2+102.4x3 Polynomial interpolation y(x)=102.473.88x+5.406x2+3.150x3 Polynomial interpolation y(x)=3.150+5.406x73.88x2+102.4x3 Least squares approximation y(x)=102.473.88x+5.406x2+3.150x3 NOTE: Equivalent Python commands are A=xdat**arange(0,4)u=lstsq(A,ydat,rcond=None)[0]
