#### probability - How to generate a random vector in octave

X = rand(s, ___) generates numbers from random number stream s instead of the default global stream. To create a stream, use RandStream. Specify s followed by any of the argument combinations in previous syntaxes, except for the ones that involve like. This syntax does not support the like

#### Octave/Matlab: Generating Random Numbers In Range

16.5 Random Matrices. This section describes the basic generators for random matrices in Octave. Additional random distributions can be found in section 24.7 Random Number Generation.. Loadable Function: rand (x) Loadable Function: rand (n, m) Loadable Function: rand ("state", x) Loadable Function: rand ("seed", x) Return a matrix with random elements uniformly distributed on the interval …

#### GNU Octave: Special Utility Matrices

rande in octave
If you read the documentation of rand in both Octave and MATLAB, it is an open interval between (0,1), so no, it shouldnt generate the numbers 0 or 1.. However, you can perhaps generate a set of random integers, then normalize the values so that they lie between [0,1].So perhaps use something like randi (MATLAB docs, Octave docs) where it generates integer values from 1 up to a given maximum.

You may also initialize the state vector from an arbitrary vector of length ≤ 625 for v.This new state will be a hash based on the value of v, not v itself. By default, the generator is initialized from /dev/urandom if it is available, otherwise from CPU time, wall clock time, and the current fraction of a second. Note that this differs from MATLAB, which always initializes the state to the

#### Octave Programming Tutorial/Loops and conditions

I have a bunch of mutually exclusive events (say 100) and I want to assign random probabilities (non-zero and hopefully with a normal distribution) to them such that their probabilities sum up to 1. Is there a way to do that in Octave? I know of rand(1,100) but I do not know if it is possible to make sure that the values sum up to a constant.

#### GNU Octave Version 5

26.5 Random Number Generation. Octave can generate random numbers from a large number of distributions. The random number generators are based on the random number generators described in Special Utility Matrices. The following table summarizes the available random number generators (in alphabetical order).

#### Uniformly distributed random numbers - MATLAB rand

I am going to be using Octave for illustration. The same commands will work in Matlab. We will be using randi() command for generating random numbers in range. The syntax is randi([start,end]). For example, I want to generate a random number between -10 and 10. So I type randi([-10,10]) on the Octave

#### Octave - General - Equivalent RandStream() in Octave?

rande in octave
The rand( ) function generates random numbers between 0 and 1 that are distributed uniformly (all numbers are equally probable). If you attempt the extra credit, you likely will need to use the rand( ) function. rand(1) – generates a single random number rand(N) – generates a …

can in Octave 5 be simplified to range = [ intmin(x), intmax(x) ]. The path handling functions no longer perform variable or brace expansion on path elements and Octave’s load-path is no longer subject to these expansions. A new printing device is available, "-ddumb", which produces ASCII art for plots.

There is no equivalent in Octave yet, but the function is typically not that essential. You can probably modify the original code to not use RandStream at all.
