With Octave 3.4.x, I tried ran the attached "rick.m" and obtained ...

rick
names =
{
 [1,1] = text1
 [2,1] = text2
 [3,1] = text3
}
equation =
{
 [1,1] = eq1=a+b*c
 [2,1] = eq2=b+c*d
 [3,1] = eq3=c+a*a
}

Since you are seeing "feval: function `print_usage' not found", it appears that there are two problems.

First, textread() or something it calls is throwing an error via print_usage(). I don't think textread.m was part of Octave's core functions when Octave-3.2.4 was released.

What do you get when you type "which textread" ?

>>> which textread

`textread' is a function from the file /usr/lib/octave/packages/3.2/io-1.0.9/x8

6_64-pc-linux-gnu-api-v37/textread.oct

 

Do you know where you got this function? Perhaps it is not compatible with 3.2.4 ?

ubuntu software center standard software
 

Secondly, it appears that print_usage() is not in your path.

What do you get when you type "path" ?

>>> path
