介绍了两种三角小波Sin-cosine小波和CAS小波,通过数值例子,对两种小波的函数逼近性能进行了比较,在同等条件下几乎具有相同的逼近精度。
Two kinds of triangular wavelet Sin-cosine wavelet and CAS wavelet are introduced. By numerical example, the function approximation performance of the two wavelet is compared, and almost the same approximation accuracy under the same conditions.
