You are probably looking for the function ''lookfor''. This function searches the help text of all functions for a specific string and returns a list of functions. Note that by default it will only search the first line of the help text (check ''help lookfor'' at the octave prompt for more). The following example helps to find the function to calculate correlation coefficient in a matrix: | You are probably looking for the function ''lookfor''.

Also, there's a high chance that the function name has a suggestive name, and so you can try auto-completion to get some hints. For the previous example, typing ''corr'' at the octave promp followed by pressing [Tab] twice would suggest the following: | Also, there's a high chance that the function name has a suggestive name, and so you can try auto-completion to get some hints.
