Sum of harmonics For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that:- The frequencies of the harmonic components are unevenly spaced-...

Brownian Dynamic Simulation to Determine Rheological Properties of FENE Dumbbell Suspensions The two programs perform Brownian Dynamic simulations to compute rheological properties of FENE dumbbell suspensions. When the applied flow is shear flow, we calculate the first and second normal stresses as well as the viscosity. For the case of an applied extensional flow, we obtain the value...

Best polynomial approximation in uniform norm For a given real-valued function of one real variable on an interval, the code calculates the best approximation in the uniform (max) norm by a polynomial of a given degree. Approximating in a uniform norm is much computationally harder compared to the standard least squares fit, but gives eye...

Binary reader for PZFlex .flxhst input files This code runs through the data array twice, initially to parse the FORTRAN records to ensure the integrity of the data, and then to read in the data. The function automatically determines the difference between 32-bit and 64-bit data. Additionally, calling the function without an input argument...
