Re: Functions in Octave

[Fausto Arinos de A. Barbuto]

Hi James,

As I wrote, Source2.m was ported from Matlab and I obviously had to

adequate it to Octave. Then several "end" commands in the original

Matlab code were replaced by "endfunction", "endfor" and "endif"

whenever and wherever required. But that was it. The logic of both

Matlab and Octave scripts is the very same however.

As expected, Source2.m works if I write BporLinhas.m and BporColunas.m

as separate files. But I don't want that. I want the functions to sit

inside Source2.m so that they can be readily visible/editable.

Lastly, the big question: testefun.m works and I hadn't to write its

two functions as separate files. Why?

Thanks for your reply.

Fausto

I just tried your Source2.m file in Matlab, and I got the following error:

>> source2
Error: File: source2.m Line: 87 Column: 1
Function definition is misplaced or improperly nested.

Which I expected, since I didn't think that Matlab supported multiple
function definitions in the same file.  Are you sure that your
Source2.m, as written, works in Matlab?  If you write each of your
functions in separate files named BporLinhas.m and BporColunas.m and
then run your Source2.m function (in Octave), what happens then?  Make
sure that either your current directory is the same directory as the
three files, or that the path contains that directory.

Hope this helps,

James Sherman
