Wavelet Precise Time-integration Method for Heat Conduction Equation
Ya Wang · Journal of Chongqing Institute of Technology · 2007
This paper takes heat conduction equation as example and presents a wavelet precise time-integration approach to solving linear parabolic equations.In this method,the quasi-shannon wavelet collocation method is given to make the spatial domain discrete and the system of or-dinary differential equation for time is built.Then wavelet precise time-integration approach is used to solve the system of equation.Numerical examples show that,compared with other method, this approach has the advantages of simple computational format,numerical stability and higher precision.
