The value +c of N is chosen, the highest polynomial to be used in the +c approximation. Then the function to be approximated is +c evaluated at the N+1 points XJ which are the zeroes of the N+1-th +c Chebyshev polynomial. Let these values be denoted by F(XJ). +c +c The coefficients of the approximation are now defined by +c +c C(I) = 2/(N+1) * sum ( 1 <= J <= N+1 ) F(XJ) T(I),XJ) +c +c except that C(0) is given a value which is half that assigned +c to it by the above formula, +c +c and the representation is +c +c F(X) approximated by sum ( 0 <= J <= N ) C(J) T(J,X) +c +c Now note that, again because of the fact that the Chebyshev polynomials +c have maximum absolute value 1, if the higher order terms of the +c coefficients C are small, then we have the option of truncating +c the approximation by dropping these terms, and we will have an +c exact value for maximum perturbation to the approximation that +c this will cause. +c +c It should be noted that typically the error in approximation +c is dominated by the first neglected basis function (some multiple of +c T(N+1,X) in the example above). If this term were the exact error, +c then we would have found the minimax polynomial, the approximating +c polynomial of smallest maximum deviation from the original function. +c The minimax polynomial is hard to compute, and another important +c feature of the Chebyshev approximation is that it tends to behave +c like the minimax polynomial while being easy to compute. +c +c To evaluate a sum like +c +c sum ( 0 <= J <= N ) C(J) T(J,X), +c +c Clenshaw's recurrence formula is recommended instead of computing the +c polynomial values, forming the products and summing. +c +c Assuming that the coefficients C(J) have been computed +c for J = 0 to N, then the coefficients of the representation of the +c indefinite integral of the function may be computed by +c +c B(I) = ( C(I-1) - C(I+1))/2*(I-1) for I=1 to N+1, +c +c with +c +c C(N+1)=0 +c B(0) arbitrary. +c +c Also, the coefficients of the representation of the derivative of the +c function may be computed by: +c +c D(I) = D(I+2)+2*I*C(I) for I=N-1, N-2, ..., 0, +c +c with +c +c D(N+1) = D(N)=0. +c +c Some of the above may have to adjusted because of the irregularity of C(0). +c +c The formula is: +c +c T(N,X) = COS(N*ARCCOS(X)) +c +c Differential equation: +c +c (1-X*X) Y'' -

The value +c of N is chosen, the highest polynomial to be used in the +c approximation. Then the function to be approximated is +c evaluated at the N+1 points XJ which are the zeroes of the N+1-th +c Chebyshev polynomial. Let these values be denoted by F(XJ). +c +c The coefficients of the approximation are now defined by +c +c C(I) = 2/(N+1) * sum ( 1 <= J <= N+1 ) F(XJ) T(I),XJ) +c +c except that C(0) is given a value which is half that assigned +c to it by the above formula, +c +c and the representation is +c +c F(X) approximated by sum ( 0 <= J <= N ) C(J) T(J,X) +c +c Now note that, again because of the fact that the Chebyshev polynomials +c have maximum absolute value 1, if the higher order terms of the +c coefficients C are small, then we have the option of truncating +c the approximation by dropping these terms, and we will have an +c exact value for maximum perturbation to the approximation that +c this will cause. +c +c It should be noted that typically the error in approximation +c is dominated by the first neglected basis function (some multiple of +c T(N+1,X) in the example above). If this term were the exact error, +c then we would have found the minimax polynomial, the approximating +c polynomial of smallest maximum deviation from the original function. +c The minimax polynomial is hard to compute, and another important +c feature of the Chebyshev approximation is that it tends to behave +c like the minimax polynomial while being easy to compute. +c +c To evaluate a sum like +c +c sum ( 0 <= J <= N ) C(J) T(J,X), +c +c Clenshaw's recurrence formula is recommended instead of computing the +c polynomial values, forming the products and summing. +c +c Assuming that the coefficients C(J) have been computed +c for J = 0 to N, then the coefficients of the representation of the +c indefinite integral of the function may be computed by +c +c B(I) = ( C(I-1) - C(I+1))/2*(I-1) for I=1 to N+1, +c +c with +c +c C(N+1)=0 +c B(0) arbitrary. +c +c Also, the coefficients of the representation of the derivative of the +c function may be computed by: +c +c D(I) = D(I+2)+2*I*C(I) for I=N-1, N-2, ..., 0, +c +c with +c +c D(N+1) = D(N)=0. +c +c Some of the above may have to adjusted because of the irregularity of C(0). +c +c The formula is: +c +c T(N,X) = COS(N*ARCCOS(X)) +c +c Differential equation: +c +c (1-X*X) Y'' -
