Function Minimizes Sum

For an input of n equations, it converges to the solution.For an input of >n equations, there is no exact solution. In this case, the function minimizes sum( (individual equation errors).^2)

This views style plugin lets you display views results as a crosstab - grouping rows by one field, columns by another, and using an aggregate function (count, sum etc) of a third field for the table data.For example, this module will take a table view with linear output like:User Content Type...

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...

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-...

In functional programming, currying is a way to bind arguments with a function and wait for the rest of the arguments to show up later. You "curry in" the first few parameters to a function, giving you a function that takes subsequent parameters as input and calls the original with all of those...
