The number 2 is the degree which you specify and it returns the coefficients of the polynomial in p. Note degree 2 means three coefficients. The second line then evaluates the polynomial using the coefficients in p. permaloc corporation-holland mi

WebMay 21, 2024 · In block 2, the call to polyfit() will construct a Vandermonde matrix via a call to numpy.linalg.polyvander(), a special matrix where the columns are in a geometric progression. Assuming the user ... WebFeb 20, 2024 · These are the a and b values we were looking for in the linear function formula. 2.01467487 is the regression coefficient (the a value) and -3.9057602 is the intercept (the b value). So we finally got our equation that describes the fitted line. It is: y = 2.01467487 * x - 3.9057602.
