Summary of New Features in Mathematica 8 (Mathematica Guide)

Equations and Inequalities over Domains (Mathematica Tutorial)

Mathematica normally assumes that variables which appear in equations can stand for arbitrary complex numbers. But when you use Reduce, you can explicitly tell Mathematica ...

Clean Up Data Imported from a ZIP File (Mathematica How To)

In addition to importing ZIP files stored on your machine, Mathematica can also import ZIP files directly from a URL. In most cases, processing data in ZIP files is ...

ArrayFlatten (Built-in Mathematica Symbol)

ArrayFlatten[{{m_11, m_12, ...}, {m_21, m_22, ...}, ...}] creates a single flattened matrix from a matrix of matrices m i j. ArrayFlatten[a, r] flattens out r pairs of levels ...

Band (Built-in Mathematica Symbol)

Band[{i, j}] represents the sequence of positions on the diagonal band that starts with {i, j} in a sparse array.Band[{i_min, j_min, ...}, {i_max, j_max, ...}] represents the ...

ComponentMeasurements (Built-in Mathematica Symbol)

ComponentMeasurements[m, " prop"] computes the values of property prop for each component of a label matrix m that consists of identical elements.ComponentMeasurements[image, ...

DateList (Built-in Mathematica Symbol)

DateList[] gives the current local date and time in the form {year, month, day, hour, minute, second}. DateList[time] gives a date list corresponding to an AbsoluteTime ...

DateString (Built-in Mathematica Symbol)

DateString[] gives a string representing the complete current local date and time. DateString["elem"] gives the specified element or format for date and ...

DesignMatrix (Built-in Mathematica Symbol)

DesignMatrix[{{x_11, x_12, ..., y_1}, {x_21, x_22, ..., y_2}, ...}, {f_1, f_2, ...}, {x_1, x_2, ...}] constructs the design matrix for the linear model \[Beta]_0 + \[Beta]_1 ...

Factor (Built-in Mathematica Symbol)

Factor[poly] factors a polynomial over the integers. Factor[poly, Modulus -> p] factors a polynomial modulo a prime p. Factor[poly, Extension -> {a_1, a_2, ...}] factors a ...
