Reconstruction of magnetic resonance images from data not falling on a Cartesian grid is a Fourier inversion problem typically solved using convolution interpolation, also known as gridding. Gridding is simple and robust and has parameters, the grid oversampling ratio and the kernel width, that can be used to trade accuracy for computational memory and time reductions. We have found that significant reductions in computation memory and time can be obtained while maintaining high accuracy by using a minimal oversampling ratio, from 1.125 to 1.375, instead of the typically employed grid oversampling ratio of two. When using a minimal oversampling ratio, appropriate design of the convolution kernel is important for maintaining high accuracy

DCT域的数字水印的嵌入和提取算法，针对的载入原始图像和水印图像都是二值图像(DCT digital watermarking embedding and extraction algorithm for the load are the binary image of the original image and the watermark image)

Model Predictive Control模型预测控制是目前流行的控制算法，以往的MPC算法都是要依靠S函数实现，本例使用MPC工具箱，详细说明了控制变量和状态变量的设定(Model predictive control (MPC) is a popular control algorithm at present. The previous MPC algorithms are implemented by S function. In this case, MPC toolbox is used to specify the setting of control variables and state variables)
