说明：  好的读图程序，使matlab可以迅速读出img等格式的图像，方便图像在envi与matlab之间转换(Good in image process, so you can quickly read matlab img image formats for easy image conversion between the envi and matlab)

捷联惯性导航技术中使用四元数算法实现姿态更新矩阵的求解，得到姿态角。(Strapdown inertial navigation technology using quaternion attitude update algorithm for solving the matrix, get attitude angle.)

水下信号与信息处理中，为了准确估计方位，把波束分为左右两路波束，成为虚拟阵元，然后计算方位。(Underwater signal and information processing, in order to accurately estimate the orientation of the beam into two beams around and become virtual array, and then calculate the position.)

循环谱估计算法，有FAM和SSCA，利用谱自相关函数或者互谱相关函数，可以对循环谱循环进行学习或者分析。(Cyclic spectrum estimation algorithms, including FAM and SCA, can learn or analyze the cyclic spectrum cycle by using spectral autocorrelation function or cross-spectral correlation function.)

二维离散小波变换(Mallat快速算法)对图像进行二维离散小波变换, 变换级数大于等于3级,然后进行阈值化处理(阈值约为10左右),再统计系数中0的个数（百分比表示）并进行重构, 最后计算重构图像的峰值信噪比(PSNR). 数据：灰度图像lena.bmp或其它图像, 滤波器系数可以调用matlab中的wfilters函数获得, wfilters函数的使用请在matlab中help wfilters.(Two-dimensional discrete wavelet transform (Mallat fast algorithm) two-dimensional discrete wavelet transform image transformed series is greater than or equal to 3, and then processing thresholding (threshold of about 10 or so), the number of re statistical coefficient 0 ( reconstruct the final calculation of the peak signal-to-noise ratio (PSNR) of the reconstructed image data: the grayscale image lena.bmp or other images, the filter coefficients can call matlab in wfilters function to obtain, wfilters function, expressed as a percentage) in matlab help wfilters.)
