用Dijstra算法计算最短路径的MATLAB程序(Shortest path algorithm with Dijstra the MATLAB program)

实现了时分复用,并在信道中加入高斯白噪声(Achieved a time-division multiplexing, and in the channel by adding Gaussian white noise)

A very small 250-line library (written entirely in MATLAB) that allows multiple MATLAB programs to talk to each other, so that hundreds of processors can work together.

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

现代信号谱分析 capon 算法MATLAB例程(spectral analysis of signals)

An efficient algorithm for identification of PIL on Solar Dynamic Observatory (SDO) Helioseismic and Magnetic Imager (HMI) magnetograms. Detailed description will appear in the paper: Volobuev, D.M. Polarity-Inversion Line Preceding X-class Flare, Solar Physics, Initial data (65 megabyte .fits magnetograms) can be downloaded from http://hmi.stanford.edu/ - Model_test_PIL_Open.m script - calculates parameters of the example(simulated S-curve) - SDO_PIL_Open.m script - identifies PIL on SDO magnetogram and calculates its parameters - 5 functions are used within these scripts

calculate the 3d voxels (in 2d pixel)

source code in Matlab, function for image thinning, using 2 different algorithm for image thinning. So you can compare that.
