MATLAB程序设计数据统计描述和分析MATLAB programming statistical description and analysis of data(MATLAB programming statistical description and analysis of MATLAB programming statistical description and analysis of data)

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0, i.e. it returns the vector A=(a,b,c,d,e,f). To convert this vector to the geometric parameters (This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.

MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral / staggered A-B method, including attenuation modeled with two relaxation mechanisms. This example demonstrates harmonic generation within a plane wave given a B/A parameter of 5.2. To increase the distance of propagation, scale the sample grid (num_axpts) by a factor(s) of 2.( MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral /staggered A-B method, including attenuation modeled with two relaxation mechanisms.

有关于相位，频率，等数字调制技术识别的MATLAB代码，(Have on the phase, frequency, and other digital modulation techniques to identify the MATLAB code,)

matlab百例.相信一定有你需要的.大家放心进来(Matlab 100 cases. I believe we have your needs. Come look at the rest assured)

编码是在MATLAB下编写的，可以在MATLAB上直接运行，我没有在分类中找到MATLAB，所以选择了c++，希望管理员能分下类。这款编码是计算水准测量中计算条件平差的。(The code is written in MATLAB, you can run directly in MATLAB, MATLAB, I did not find in the classification so chose c++, I hope that the administrators in the next class. This code is calculated in the calculation leveling adjustment of condition equations.)

OFDM系统的基础代码集。都是基础程序，希望对大家有用(OFDM system code base set. Are based procedures in the hope that it may be useful to)

these codes implement out of band carrier de activation for OFDM. the number of subcarriers is flexible.

the use of coherent space-frequency coding in orthogonal frequency division multiplexing (OFDM)-based frequency-selective multiple-input multiple-output (MIMO) antenna fading channels has been proposed. Acquiring knowledge of the fading coefficients in a MIMO channel is already very challenging in the frequency-flat (fast) fading case. In the frequency-selective case, this task becomes significantly more difficult due to the presence of multiple paths, which results in an increased number of parameters to be estimated. In this paper, we address code design for noncoherent frequency-selective MIMO-OFDM fading links, where neither the transmitter nor the receiver knows the channel. We derive the code design criteria
