合流超几何函数是处理较为复杂的语音处理算法中的较为常见的程序，它在MATLAB中能够正确实现相对有些困难，附上的程序能够在语音增强算法中正确运行。(Confluent hypergeometric function is dealing with more complex voice processing algorithms in the more common procedures, it can be correctly implemented in MATLAB relatively somewhat difficult, enclosed in a speech enhancement algorithm program can run correctly.)

Example of a two-dimensional Gabor filterIn image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filter are similar to those of human visual system, and it has been found to be particularly appropriate for texture representation and discrimination. In the spatial domain, a 2D Gabor filter is a Gaussian kernel function modulated by a sinusoidal plane wave. The Gabor filters are self-similar – all filters can be generated from one mother wavelet by dilation and rotation
