3.1.1 Numeric Objects
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 realmin
,
realmax
, and eps
, respectively.
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 section 8.1 Index Expressions.
See section 4 Numeric Data Types, for more information.
