Given a vector x, construct in Python the following matrix:
Here, xi
are the components of the vector x (numbered from zero). Given a vector y, solve in
Python the linear equation system Va = y. Let the components of a be denoted by ai
, i = 0, …,
5. Write a function poly, which has a and z as input and which computes the polynomial:
Plot this polynomial and depict in the same plot the points (xi
, yi
) as small stars. Try your
code with the vectors:
x = (0.0, 0.5, 1.o, 1.5, 2.0, 2.5)
y = (-2.0, 0.5, -2.0, 1.0, -0.5, 1.0)
