5.3 String Operations

Octave supports a wide range of functions for manipulating strings. Since a string is just a matrix, simple manipulations can be accomplished using standard operators. The following example shows how to replace all blank characters with underscores.

quote = ...
  "First things first, but not necessarily in that order";
quote( quote == " " ) = "_"
⇒ quote =
    First_things_first,_but_not_necessarily_in_that_order

For more complex manipulations, such as searching, replacing, and general regular expressions, the following functions come with Octave.

• Common String Operations
• Concatenating Strings
• Splitting and Joining Strings
• Searching in Strings
• Searching and Replacing in Strings
