3.1.1 Numeric Objects
Octave's built-in numeric objects include real and complex scalars and matrices. All built-in 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.
