Using the C++ Math Library

Array Input and Output

Overview

This chapter describes how to:

• Use C++ input and output streams to read and write from input and output from files.
• Use fscanf() and fprintf() to read and write from input and output from files.
• Read data from and write data to MAT-files

The C++ I/O stream operators are more convenient than functions like fprintf(), because they are more consistent, flexible, and extensible. Because each object in a C++ program is responsible for printing itself to a stream and reading itself from a stream, objects have complete control over their own printed format. New objects can be added without changing the code in the basic streams mechanism.

In addition, the MATLAB C++ Math Library also supports the load() and save() routines which enable you to import and export data in MAT-file format. The library stream I/O implementations do not support .
