摘要
采用具有良好紧支性的样条小波基,在有限区间上进行小波分解,用配点法求出任一空间中的分解系数,并且对一有奇异解的微分方程进行了奇异性探测,明显地看出小波空间的增加就是在更高的分辨率下对解的修正.
A cubic spline wavelet base with a good property of compact support is used to have a wavelet decomposition for the interval. Collocation methods are adopted to obtain coefficients of decomposition in any space. The search for differential equation with singular solution shows that the increase of space of wavelet is a revision of higher resolution ratio.
