Octave's built-in numeric objects include real, complex, and integer
scalars and matrices. All built-in floating point numeric data is
currently stored as double precision numbers. On systems that use the
IEEE floating point format, values in the range of approximately
2.2251e-308 to 1.7977e+308
can be stored, and the relative precision is approximately
2.2204e-16.
The exact values are given by the variables <code>realmin</code>,
<code>realmax</code>, and <code>eps</code>, respectively.
<p>Matrix objects can be of any size, and can be dynamically reshaped and
resized. It is easy to extract individual rows, columns, or submatrices
using a variety of powerful indexing features. See <a href="Index-Expressions.html#Index-Expressions">Index Expressions</a>.
