Software Listing: Integral

This code computes the approximation of the convolution integral (*) between two functions, f(t) and g(t), sampled at the times t1,t2,...,tm (unit spacing), via the trapezoidal quadrature rule. To compute the integral with other than unit spacing, multiply the result by the spacing increment. Computation is very fast because it has been used the built in function conv(). To conv() result has then been added what misses for trapezoidal approximation. Convolution integral is defined as: (*) h(t)=int{f(tau)*g(t-tau)}dtau..

Integral Calculator Level 1 is an easy to use tool that was designed in order to compute definite integrals of differentiable functions. Numerical values are calculated with precision 15 digits. Also uncertainty of result is computed.

The calculator does not make any symbolic integration and any analytical guessing. The algorithm is purely numerical. It has some advantages and disadvantages. For example, the algorithm gives too big uncertainty for cos(x) on [300, 500], although symbolical integrator easily gives answer -sin(500)+sin(300). But symbolic integration does not give answer for e^cos(x) on [-1,1].

View factor is a MATLAB function that uses the CDIF (contour double integral formula) to calculates view factors between planar surfaces(polygons), no matter what are the shape and the orientation of the two figures. All you need to enter is the coordinates of the vertices that define the outlines of the two figures and the level of precision desired (number of significant digits). example: Use the following command to calculate the view factors between two parallel triangles of coordinates (0,0,0),(1,0,0),(0,1,0) and (0,0,1),(2,0,1),(0,2,1) with a precision of 6 significant digits. [vfactor12,vfactor21,area1,area2]=viewfactor([[0,0,0];[1,0,0];[0,1,0]],[[0,0,1];[2,0,1];[0,2,1]],6).

We present here a program Fie that solves numerically Fredholm integral equations of the second kind on an interval [a,b] to a specified, modest accuracy. Test programs are also included for the various cases. The program TestAll, with no input parameters, can be used to illustrate the various types of integral equations handled by Fie. The kernel function K(s,t) is to be moderately smooth on [a,b]doOCo[a,b] except possibly across the diagonal s=t. If the interval is finite, Fie provides for kernel functions that behave in a variety of ways across the diagonal, viz. K(s,t) may be smooth, have a discontinuity in a low-order derivative, have a logarithmic singularity, or have an algebraic singularity.
