Boundary

The method uses finite differences to solve Laplace equation and matrix inversion to solve the resulting system of linear algebraic equations. The rectangular plate has both dimensions set equal to unity. Each dimension is discretized and the total number of nodal points is equal to 29*29. To... Platforms: Matlab

SETTPI(NUM,DEN,W,P) plots the stability boundary locus L(KP,KI,W)in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W) gridding becomes important. For a specific... Platforms: Matlab

THz radiation pulse simulation by means of 1D-FDTD. Pulse is generated by hard source point in free space. Mur's radiation boundary's are placed at both sides of the simulating region.Sorry for my English!!! Platforms: Matlab

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement.... Platforms: Matlab

This toolbox implements the methods of [1] and [2] to design H-infinity controllers for linear spatio-temporally invariant, or multidimensional (MD), systems. Utilities are also provided for the following types of operations on MD systems:1. System description (MD systems are specified via a... Platforms: Matlab

These scripts compute the sediment transport outside the surf zone in the beach. The procedure and equations can be reviewed on the Coastal Engineering Manual.

The correlation coefficient calculation is implemented not with built-in function corr or corr2 but with conv2. Function corr is relatively slow for template matching purpose and it is also required extra considerations on controlling the boundary and selecting region of interest on the frame...

voronoiSkel uses only the pixel on the boundary of the objects, and therefore is very efficient for thick objects (efficiency scales with the object's radius, rather than its area). However, it might be sensitive to small defects, if they are on the boundaries (or small holes inside the... Platforms: Matlab

This script generates artificial spatial data using a first order spatial autoregressive process (AR1)The process isX(i,j) = PHI*(X(i,j-1)+X(i,j+1)+X(i-1,j)+X(i+1,j) + errorTo generate a 10x10, periodic spatial pattern, with normal error distribution, and a variance of SIGMA, the command...

In reachability analysis, one is interested in computing the set of states that can be reach by the system from a set of initial states. A straightforward way to approximate this set is to simulate the system for all the boundary points of the initial set. This demo illustrate how Simulink... Platforms: Matlab

In large scale mapping projects with numerous satellite images, it is useful to have a vector file depicting the boundary of the images.
