摘要：

A method is given for the numerical solution of some partial differential equations by expansion in double Chebyshev polynomials. This is accomplished by starting with Chebyshev approximation for the highest partial mixed derivative and generating approximation to the lower-order derivatives through integration by using El-Gendi method. © 1990, Taylor & Francis Group, LLC.
