Radix 2 FFT using Decimation in Frequency
Truly Appreciates the Wonder Geniuses Joseph Fourier & Cooley Tuckey
This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal...
D = decimmtx(x,N)
decimates the given signal by a factor of N.
A figure for band pass decimation with desired signal bandwidth B, where Fi_B is anolog frequence point corresponding to B, Fs_B is sample rate corresponding to B.
The color parts are forbidden areas.
StructTriMesh is a tool to build structured triangular mesh on rectangle dataset. This is useful in avoiding delaunay 2D in
order to improve speed performances.
It can be used for graphical purposes, fem analysis, sedata structuresd-deTZ
StructTetraMesh is a tool to build structured tetreaedral mesh on cuboid dataset. This is usefull in avoiding delaunay 3D triangulation that for this kind of dataset are particularly slow and numerically unstable.
This tool allows a huge...
MESH_LAPLACIAN: Laplacian of irregular triangular mesh
Useage: [lap,edge] = mesh_laplacian(vertex,face)
Returns 'lap', the Laplacian (2nd spatial derivative) of an irregular triangular mesh, and 'edge', the linear distances...
The function femTriangularMeshGenerator() generates triangular mesh for a rectangular shape structure for Finite Element analysis.
The outputs are:
coords = x and y coordinates of each element nodes
cT = nodal connectivity
Assess the quality of a triangle mesh using a simple indicator.
This function smooths a triangulated Mesh / Patch.
Supports accurate curvature flow smoothing. Which smooths in the direction of the normal keeping the edge ratio's the same.
Also supports Laplacian smoothing with inverse...
This function "refinepatch" can refine any triangular mesh surface ( patch) with 4-split spline interpolation, see screenshot.
The spline interpolation of the face edges is done by the Opposite Edge Method,...
The program does interpolation or decimation on a given 1-d data in an array.
Given X with sampling rate Ft Hz and is used to generate another sequence Y with sampling rate Ft' Hz, then Sampling Rate ratio R is given by,
Neural Mesh is a purely PHP, fast, easy Neural Network Manager, Administrator and Framework.
The highlight of the project is that it allows you to integrate Artificial Intelligence into your applications, quickly and easily, no matter...
The mesh programming language is a universal styling language that utilizes the Java framework. It contains many novel features, rigorous type checking, and integrated extendability.
The decimation Tools Set (DTS) generate automatically efficient implementations of Linear Feedback Shift Registers (LFSRs) in both software and hardware.
The Node Mesh abstracts data into its most modular components. The Node Mesh gives you the ability to make large scale technical changes much faster than can be done using traditional relational models.
MATLABs most commonly used 3-d plotting tools surf and mesh require rectangular grids to plot in 3-d, not x,y,z triples. This function converts arrays of x,y,z triples into rectangular grids to use with surf, mesh, etc.
This submission is based on Alexandre Gramfort's "matlab-mesh-to-pdf-with-3d-interactive-object". His program allows meshes to be converted into 3D PDF figures. However, his code only allows a single layer to be converted, and does not...
MESH2D is a toolbox of 2D meshing routines that allows for the automatic generation of unstructured triangular meshes for general 2D geometry.
An iterative algorithm is used that attempts to optimise the mesh topology/vertex position to...
This function uses a vectorized version of the marching cubes algorithm to compute a triangulated mesh of the isosurface within a given 3D matrix of scalar values at a given isosurface value. The output is a triangulated mesh specified in terms of...
Simple function that tells if a point is inside of a mesh, be it concave or convex
The algorithm just finds the intersection points between the facets and a vertical line that passes through the original point. Depending on the relative...
