用于字母识别实用的matlab程序，在图像文字识别中得以应用。(The practical matlab program for letter recognition can be used in image recognition.)

用matlab实现的26个字母识别。基于BP算法的字母识别其容错性和识别率相对较高，在有噪声的情况下训练其识别出错率也相应增加，许进一步改进。(26 letter recognition implemented with MATLAB.The letter recognition based on BP algorithm has a relatively high fault tolerance and recognition rate, and the error rate of recog
