Sum

Built-in "sum" function, as well as add.reduce functions in Numeric/numarray introduce a large error when summing large arrays of like elements. This script contains a function that makes sums with error less than 1e-15. It doesn't use any additional memory (although it destroys the data...

Disclosed are methods to compute the precise value of the logarithm of a sum and the logarithm of a subtraction.A number of practical problems can result in having too big or small values in intermediate values of a calculation. Then one tries to take logarithm of these values and operate on...

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-...

Intro: This function generates random samples for k Xi's where Xi>=0 and the sum Xi is fixed at g. We assume that X's are independent and follow an identical distribution with a CDF function myCDF(x) and an inverse CDF function myICDF(p). I needed a function that works for Xi>=0. So here it is....
