说明：  利用ABC(人工分群算法)求解数值计算问题。(ABC (artificial clustering algorithm) is used to solve numerical problems.)

matlab仿真的GPS信号捕获程序，相关及非相关累积算法(matlab simulation of the GPS signal acquisition process, relevant and non-related accumulation algorithm)

地震勘探 谱比法Q值估计（谱比法）谱比法Q值估计是地震勘探的常用方法(Seismic spectral ratio Q value estimation (spectral ratio))

说明：  这是一本精通Matlab的电子书，这本书深入浅出的讲述Matlab这个工具的使用。(This is a proficient in Matlabs books, this book describes in simple terms the use of this tool Matlab.)

该函数用来计算任意函数的一阶偏导数(数值方法)，希望对大家能够有所帮助吧~~(This function is used to calculate any function of the first order partial derivative (numerical method), we want to help it ~ ~)

说明：  对于已定义的包含从0到15的整数的列向量xsym，就可以利用modem.qammod对象的modulate方法来调制它。其中M值为16，亦即为码字表的大小。 对已调制信号可采用awgn函数添加加性高斯噪声。其中比特能量与噪声功率谱密度的比值，Eb/N0，设置为10dB。 (The method comprising modulate integer from column vectors xsym 0 through 15, can use the defined object modem.qammod modulating it. Wherein M is 16, i.e., a codeword size of the table. Modulated signal can be used for awgn function to add the additive Gaussian noise. Wherein the ratio of bit energy to noise power spectral density, Eb/N0, is set to 10dB.)
