Help with 2.9.9
Tue, 28 Nov 2006 10:08:40 -0500
I have just installed Octave 2.9.9 on a Mac Power PC OS X 10.4 via High
Performance Computing. So far it does not work.
Problem 1. I don't know how to set the LOADPATH anymore. I had a .octavrc file
in my home directory that read
PS1 = "\\s> ";
LOADPATH = [LOADPATH, ':~/octave/oct//:~/octave/m//'];
This worked fine in Octave 2.73. Now I get the error messages
error: `LOADPATH' undefined near line 3 column 13
error: evaluating assignment expression near line 3, column 10
error: near line 3 of file `/Users/vic/.octaverc'
Question 1. How do I set my LOADPATH now? How do I set PS1 to what I want?
Problem 2. Things were working fine in 2.73, but I switched to 2.9.9 in hopes
of being able to solve triangular systems efficiently using the "matrix_type"
fuction. My first test of the function was with this code:
R = [
ans = Positive Definite
warning: Invalid matrix type
So far so bad! (1) Obviously the matrix is NOT postive definite.
Question 2. How do you set the matrix_type?
The documentation reads (in part)
-- Loadable Function: A = matrix_type (A, 'upper', PERM)
It seems to me that 'upper' IS a valid matrix type. And no, the problem is not
because R is not upper triangular. The same error occurs if R = [ 1 0; 0 4].
And capitalizing the first letter to 'Upper' makes no difference either.
Thanks for any advice you can give me. - Vic
