MATLAB® and Its Applications in Engineering: [Based on MATLAB 7.5 (R2007b)]

5.6. Low-Level Input–Output Functions

There are a number of low-level file input–output functions in MATLAB which are based on the input–output functions of ANSI Standard C Library. The functions are generally categorized as

1. File opening and closing functions

2. Binary input–output functions

3. Formatted input–output functions

These are listed in Table 5.2.
