Re: Installation problem of octave 4.2.1 on Windows 10

Dear Svetlana & Sourav,

I have also installed Octave 4.2.1 pre-built Windows 10 version on my Acer Laptop Aspire IV, running Windows 10. I am able to use for many hours without any trouble. Let me know if any other information that will be useful.

This is an unhelpfully uninformative error message. Personally I would test for this issue with a new OS user to rule out issues with how your Octave settings are saved under that particular user.

Svetlana

I'd like to generate a matrix like this (small version to give you the idea):

0 0 0 (three columns in this example)
0 0 1
0 0 2
0 0 3
.
.
.
9 9 8
9 9 9

Could anyone here show me how to do this efficiently?

thanks in advance

This is the decomposition on base 10, a way of doing it is

nc = 3; # number of columns
base = 10;
i = (0:(base^nc-1)).'; # row index - 1
counter = mod( floor (i ./ base.^[(nc-1):-1:0]), base);

it should work for any integer base, but please do check.

THanks. I have another question.
As I am new to ML, I am looking for some inputs about the right method to
use for a problem statement.
However, I have had little help from redditt forum on this.

Do you know a forum where people are more active and willing to help?

As far as NNET is concerned, there has been a recent GSOC project intended
to revive the NNET package for Octave last year.

The student and mentor of this project are in CC.

Dear Juan,
I bumped into the following problem. I changed your code to a function
like this:

function [counter] = decomp (base, nc)
i = (0:(base^nc-1)).'; # row index - 1
counter = mod( floor (i ./ base.^[(nc-1):-1:0]), base);
endfunction

It works fine for a lot of cases but the case I want to use is
problematic as you can see here:
result=decomp(10,9);
error: out of memory or dimension too large for Octave's index type
error: called from
decomp at line 27 column 9

in fact I need decomp(10,10)

do you see a workaround for this problem?

kind regards,
