Generation of higher order pseudospectral integration matrices
This paper reports a pseudospeudospectral method based on integrated Chebyshev polynomials. The presented method is applied to numerically solving initial and boundary value problems of linear integral and integro-differential equations. The suggested integration matrix leads to highly accurate results as shown in the given tables, better than those obtained using the original matrix and other modified matrices. The proposed method is much more accurate and superior to the other conventional methods.
