Description: This function computes Euclidean distance transform for 3D binary image with non-trivial aspect ratio (i.e. anisotropic pixels). The algorithm uses fast optimized line-scans and is actually faster than MATLAB s BWDIST implementation of search on optimized kd-tree for many cases. It also uses cell-array representation for internal data, and thus is less demanding to physical memory. Platform: |

Description: 这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible).
The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot).

Description: 二阶欠定盲分离程序，经典，完整，让您一目了然，请放心使用，原汁原味的matlab代码及详细的英文标注。-ack sobi_cp3
Second Order Blind Identification via Candecomp/Parafac order-3 (CP3)
to solve linear instantaneous Blind Source Separation (BSS).
sobi_cp3 allows to handle the exactly-determined, the over-determined and
several under-determined problems.
sobi_cp3 computes a set of K covariance matrices of the observed signals.
Then, the mixing matrix is estimated by joint-approximate-diagonalization (JAD)
of this set of matrices.
The JAD problem is solved by computing the CP3 decomposition of the third-order
tensor (3-way array) built by stacking the covariance matrices along the third
dimension.
It exploits the fact that JAD is a particular case of CP3 where the slices of
the tensor are symmetric, i.e., the mode-1 and mode-2 loading matrices
of the decomposition are identical.
Here the cp3 model is fitted by ignoring this symmetry, via an alternating
least squares (ALS) coupled with exact line search.
Thanks to powerful uniqueness properties of CP3, estimation of t Platform: |
