Setting Up External Functions to Be ... (Mathematica Tutorial)

If you have a function defined in an external program, then what you need to do in order to make it possible to call the function from within Mathematica is to add ...

The Secant Method (Mathematica Tutorial)

When derivatives cannot be computed symbolically, "Newton's" method will be used, but with a finite difference approximation to the Jacobian. This can have costs in terms of ...

Secure Socket Layer (SSL) (DatabaseLink Tutorial)

Secure Socket Layer (SSL) is a protocol for providing secure transactions between servers and clients. It uses a certificate to identify one or both ends of the transaction. ...

The Database Explorer (DatabaseLink Tutorial)

The Database Explorer is a graphical interface to DatabaseLink. It provides a number of useful functions, such as managing connections and working with the data in a ...

Transactions (DatabaseLink Tutorial)

Some database operations involve carrying out a sequence of database commands. For example, information in two different tables may need to be updated. In these cases it may ...

Exp (Built-in Mathematica Symbol)

Exp[z] gives the exponential of z.

LQRegulatorGains (Built-in Mathematica Symbol)

LQRegulatorGains[ss, {q, r}] gives the optimal state feedback gain matrix for the StateSpaceModel object ss and the quadratic cost function with state and control weighting ...

DensityHistogram (Built-in Mathematica Symbol)

DensityHistogram[{{x_1, y_1}, {x_2, y_2}, ...}] plots a density histogram of the values {x_i, y_i}.DensityHistogram[{{x_1, y_1}, {x_2, y_2}, ...}, bspec] plots a density ...

Sum (Built-in Mathematica Symbol)

Sum[f, {i, i_max}] evaluates the sum \[Sum]i = 1 i_max f. Sum[f, {i, i_min, i_max}] starts with i = i_min. Sum[f, {i, i_min, i_max, di}] uses steps d i. Sum[f, {i, {i_1, i_2, ...

Line Search Methods (Mathematica Tutorial)

A method like "Newton's" method chooses a step, but the validity of that step only goes as far as the Newton quadratic model for the function really reflects the function. ...
