Mathematica expressions provide a very general way to handle all kinds of data, and you may sometimes want to use such expressions inside your external programs. A language ...

 

BaseForm[expr, n] prints with the numbers in expr given in base n.

EulerE[n] gives the Euler number E_n. EulerE[n, x] gives the Euler polynomial E_n (x).

Median[list] gives the median of the elements in list. Median[dist] gives the median of the symbolic distribution dist.

Position[expr, pattern] gives a list of the positions at which objects matching pattern appear in expr. Position[expr, pattern, levelspec] finds only objects that appear on ...

f /: lhs := rhs assigns rhs to be the delayed value of lhs, and associates the assignment with the symbol f.

Many differential equations exhibit some form of stiffness, which restricts the step size and hence effectiveness of explicit solution methods. A number of implicit methods ...

Exact global optimization problems can be solved exactly using Minimize and Maximize. This computes the radius of the circle, centered at the origin, circumscribed about the ...

You can define wavelets to plug into the wavelet analysis framework by using the correct template. A wavelet wave is of the form wfam[args], where wfam is the symbol that ...
