How can I find a 5x5 symmetric tridiagonal T matrix with eigenvalues that equals with the zero points of the fifth T5(x) Chebyshev polynom. I'm sure it is easy but I'm just a student and I would appriciate any help. Thenk you in advance. P.S.: A solution using orthogonal polynoms would be even more appriciated.
How can I display one (or more) point using plot? E.g. How can I plot the following ycoord vector: [1,2,5,4,3] (xcoord=[1,2,3,4,5])? In the maple help it was discussing function plotting only...
