Volume Of A Sphere Equation

This one line function adds up the ascii values of a string and returns the total as a checksum. Also included is a variation which returns the checksum mod 256 (so it can be used as a single byte).The same technique can be used to add up a list of numbers, or to return the average of a list...

The gliding box algorithm proposed by Tolle et al., Physica D, 237, 306-315, 2008 is used to calculate the lacunarity of a binary image.

Usage: [mfTutteMap] = TutteMap(mnTriangulation)Maintaining the existing triangulation, this function maps a surface mesh onto a planar unit circle. Tutte's algorithm [1] is used. The simple technique for finding point locations is from [2].'mnTriangulation' is an Nx3 array as returned by...

The program takes the intermediate stoichiometric matrix of a chemical reaction mechanism as the input and gives the intermediate nodes in terms of all the possible combinations of p-(q-1) reaction steps. This program is complimentary to the "Reaction Routes" program. Using both these programs a...

This function will return true if the first input structure contains the field in the second input string and in turn that field has the field given in the third input string and so on. This allows A.b.c = 2; to be checked as:isfieldRecursive(A,'b','c')ans =1Which would return false if either b...

In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All...

The MATLAB file contains a method to find the value of pi. This is just an extension of the general method of finding pi from within a circle. It uses 3D-matrices and some more stuffs, which can be very helpful for educational purposes. Also, do change the values in the file, to see for yourself,...

The velocity and shear stress versus radial position are determined for laminar flow of a power law fluid in a pipe. The shooting method is used to verify the no-slip boundary condition at the piped-deOaos wall. Once the velocity at the center is determined, the governing equation is solved...

Say you are only able to obtain a limited number of terms in a power series, as each term is increasingly difficult to obtain (ex. virial equation of state). To explore possible analytic continuations, you need an infinite series representation. A rational function is one way to prescribe this,...
