NormFunction is an option for functions such as FindFit and NDSolve which gives a function to be minimized in generating results.

There are many functions that are built into Mathematica. This tutorial discusses how you can add your own simple functions to Mathematica. As a first example, consider ...

Often a web service requires using data other than a simple string. This data could be something simple like an integer or a real. Often the data is more complex and is a ...

Mathematica by default interprets any sequence of letters or letter-like forms as the name of a symbol. All these are treated by Mathematica as symbols. Symbols with built-in ...

Within a standard interactive session, you can create "subsessions" or dialogs using the Mathematica command Dialog. Dialogs are often useful if you want to interact with ...

Numerical algorithms for constrained nonlinear optimization can be broadly categorized into gradient-based methods and direct search methods. Gradient-based methods use first ...

DeleteEdge[g, e] gives graph g minus e. If g is undirected, then e is treated as an undirected edge; otherwise it is treated as a directed edge. If there are multiple edges ...

Open opens a dialog box for opening an existing file.

MathematicaScript is an interpreter for standalone executable Mathematica scripts.

EdgeDelete[g, e] makes a graph by deleting the edge e from the graph g.EdgeDelete[g, {e_1, e_2, ...}] deletes a collection of edges from g.EdgeDelete[g, patt] deletes all ...
