9.5) Writing Text Files
The simplest way of saving array data to text files is to use the "save" command. To save data, we require a definition of the output format. For example:
[matlab]
>> A=randn(10,2) % Generate some normally distributed random numbers
>> save('random_data.txt', 'A', '-ascii') % Save as a text file
[/matlab]
Matlab has many high level functions to read and write ascii and binary data. The main functions are:
| fopen | Opens a file for reading and/or writing |
| fscanf | Read an ascii file |
| fprintf | Write an ascii file |
| fread | Read a binary file |
| fwrite | Write a binary file |
| fclose | Close a file |
