this is Illustration of linear least squares.

使用MATLAB对特定信号进行频谱分析，画出幅度和相位谱的图像，并包含卷积运算和验证程序(The use of MATLAB to carry out a specific signal spectral analysis, to draw the magnitude and phase spectrum of images, and includes the convolution operation and the verification process)

with this mscripts we are enable to perform accurately pitch detection.first with short term zerocrossing and short term energy estimation analyses we find voiced regions and then with hps algorithm, find pitch values of utterance.

it contains a matlab file with extension of .m

that is useful code for communication
