How do I install Octave on Mac. Download the appropriate Dynare package for your version of Mac OS X from the website. Install Dynare by double-clicking on the package and following the installation instructions. Mac Os Versions; Octave (itch) Mac Os X; Most of the time, installing things with MacPorts is pretty easy; however, I have found that GNU Octave can be a little tricky.

Octave Version 5.2.0 has been released and is now available for download.An official Windows binary installer is also available.For macOS see the installation instructions in the wiki.

Download and install Octave

There are a number of Open Source alternatives to the program MatLab, one of the most known alternatives is GNU Octave. When using Octave you use a command line to enter commands. Octave can be downloaded and installed from GNU Octave.

Install on Mac

If using Mac:

Install Homebrew.

Install XCode from App Store.

Open and run the XCode app to agree to the License Agreement.

Install XQuartz.

Import science packages, open the terminal and enter:

Install Octave (this takes time):

Update:

At the end of the process a summary is shown displaying the path to Octave. If following is shown:

then the path to Octave is /usr/local/Cellar/octave/3.8.1/bin/Octave Open AppleScript Editor and make a New Document. Write following:

where /path/to/octave is the path. Save the script as Octave.app, select Application when saving.

For more information see Octave for MacOS X.

As a calculator

The easiest way to get started, is to use Octave as a calculator.

The arithmetic operators are:

There are predefined constants in Octave, some of them are listed below:

constant	explanation
`pi` , `e` , `i`	Make a wild guess!
`Inf` (infinity)	Operations yielding numbers larger than the maximum floating point will give this answer.
`NaN` (not a number)	Operations that can not be defined in any reasonably way will give this answer

There are also a number of predefined mathematical functions in Octave, some of them are listed below:

function	explanation
`sin, cos, tan`	Trigonometric functions using radians
`asin, acos, atan`	Inverse trigonometric functions
`exp, log, log10`	Exponential function, natural logarithm, logarithm to the base 10
`sqrt`	Square root
`abs`	Absolute value
`round, floor, ceil`	Round to nearest integer, round down, round up
`rem`	Remainder when doing integer division

Showing more decimals

You can show more decimals by typing format long. Go back to showing few decimals by typing format short.

Exercise 1

Calculate following expressions

(sqrt[5]{200})
(dfrac{3cdot 10^{-3}}{0.001+sqrt{0.2}})
(dfrac{2^{3+sin{0.3}}+5}{10})

You should get these answers

ans = 2.8854
ans = 0.0066932
ans = 1.4819

You can see old commands by using up/down arrow keys.

Exercise 2

Guess the output of following commands, then check the answers given by Octave

1/0 0/0 tan(pi/2)
inf+inf inf-inf inf/inf inf*inf
nan+2 nan+nan

Exit Octave

Exit Octave by writing exit or quit.

Numerical variables

When evaluating the value of an expression, the result is stored in a variable called ans (answer). You can also introduce variables of your own.

By writing who you can see all variables. If you write a semi colon at the end of the line, the output is not shown.

Naming variables

Various programs have different rules for naming entities. Although some modern programs allow for all kind of characters in names, you may run into trouble if you use characters like '-' or blank. If you want to stay on the safe side, never having to bother about naming-rules for specific programs, follow these old-school rules:

The first character must be an english letter : a -z, A - Z
Some programs can handle letters like å, Æ, Ç, ü; others cannot. Use english names when programming!
The name can include numbers : 0 - 9
The name can include underscore : _

These rules apply to Octave and a number of other programs.

Assignments

When writing a=5 at the command prompt, the equal-sign should not be thought of as a logical equality; a is not equal to 5, it is assigned the value 5. Having that in mind, one can write assignments like this

The statement above would be false if it was a logical statement, it is however not a logical statement but an assignment. The right-hand-side of the statement is calculated first, the result is then assigned to the variable on the left-hand-side.

Hiding the output and repeating previous commands

You can write several commands on one line by using comma, or semi colon. By using up-arrow, you can repeat the previous command, and alter it.

You can calculate a geometric series by using up-arrow several times.

Exercise 3

Calculate the series:

[sum_{i=1}^{20} left(frac{1}{i} right)^2 ]

(The answer is 1.5962)

Exercises on Sequences

A sequence is a function with the domain being the natural numbers. A sequence can be written like this (a_0,a_1,a_2,...) or like this

Mac Os Download

[left( a_n right)_{n=0}^{infty} ]

Recurrence equations

A geometric progression can be defined in different ways. Consider the infinite geometric progression (3, 3cdot 2, 3cdot 2^2,...).

You can describe the geometric progression in two ways.

A recurrence equation:

[ left{ begin{align} a_0 &=3 a_{n+1} &=2cdot a_n, ngeq0 end{align} right. ]

Cached

An explicit formula:

[a_n=3cdot 2^n, nin mathbb{n}]

Exercise 4

Use Octave to find the limit as (nrightarrowinfty) of following sequences. Type format long to show more decimals. Try different initial values (c), do you get different limits?

[ left{ begin{align} a_0 &=c a_{n+1} &=1+frac{1}{a_n}, ngeq0 end{align} right. ]
[ left{ begin{align} a_0 &=c a_{n+1} &=sqrt{1+a_n}, ngeq0 end{align} right. ]

Try to explain your answers. If you fail, do the exercises on Calculus - Fixpoints.
