Systems of ODEs are important in various fields of science, such as the study of electricity and population biology. Like single ODEs, systems of ODEs can classified as ...

ButtonBar[{lbl_1 :> act_1, lbl_2 :> act_2, ...}] represents a bar of buttons with labels lbl_i that perform actions act_i when pressed.

Mathematica serves as a convenient and extensible environment for doing basic math. In addition to performing advanced calculations, Mathematica can also be used as a ...

One of the most common statistical models is the linear regression model. A linear model predicts the value of a response variable by the linear combination of predictor ...

QPolyGamma[z, q] gives the q-digamma function \[Psi]_q (z).QPolyGamma[n, z, q] gives the n\[Null]^th derivative of the q-digamma function \[Psi]_q^(n)(z).

PiecewiseExpand[expr] expands nested piecewise functions in expr to give a single piecewise function. PiecewiseExpand[expr, assum] expands piecewise functions using ...

Modules in Mathematica allow you to treat the names of variables as local. Sometimes, however, you want the names to be global, but values to be local. You can do this in ...

Functions like Read and Find are most often used for processing text and data from external files. In some cases, however, you may find it convenient to use these same ...

SplineClosed is an option for B-spline functions and graphics primitives that specifies whether spline curves or surfaces should be closed.

TautologyQ[bf] gives True if all combinations of values of variables make the Boolean function bf yield True.TautologyQ[expr, {a_1, a_2, ...}] gives True if all combinations ...
