- Use Matlab To Find The Coefficients Of The Cubic Polynomial Y Ax3 Bx Cx D That Passes Through The Three Points 1 (47.11 KiB) Viewed 33 times
Use MATLAB to find the coefficients of the cubic polynomial y = ax3 + bx² + cx + d that passes through the three points (x, y) = (1, 4), (4, 73), (5, 120). Store your result in a vector named coeff. Discuss your solution and indicate whether a solution exists, if so, say whether it is an exact solution or a least-squares solution. Plot the polynomial with the coefficient you found along with the given points on the same plot.
