octave

I've installed Octave and gnuplot via Homebrew, and downloaded AquaTerm.dmg. When I try to plot, I get the following message: octave:4> plot(x,y) gnuplot> set terminal aqua enhanced title "Figure 1" font "*,6" ^ `line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list` In a bash terminal set terminal , set Terminal , set term , (and the same, followed by "aqua" too) etc gives nothing. I've tried plotting again from octave having the "AquaTerm" already open, but nothing. I've tried plotting directly from gnuplot but same problem.. How can I do this "set terminal aqua"?

I need to write code that should run equally well in Octave and on MATLAB. Problem is that it needs to do some GUI stuff, which MATLAB and Octave handle completely differently. Is there a way I can detect if I'm running MATLAB or Octave, in order to call the right function? You could use the following test to differentiate Octave from MATLAB: isOctave = exist('OCTAVE_VERSION', 'builtin') ~= 0; Bernhardt Rogge There is also a hint in the wiki on the official octave.org website. They propose the following: Edit: Not all versions of Matlab support '#' for comments so I changed the example to use

I want to use octave to plot fairly simple functions with two variables like: f(x,y) = x^2 + 3y . It is very easy to plot single variable functions, but I am having a lot of trouble finding out how to do two variable functions. Does anyone know the best way of doing this? Plotting a function of two variables would normally mean a 3-dimensional plot - in MATLAB you would use the function plot3 for that. To plot your function f(x,y) in the interval [-10,10] for both X and Y, you could use the following commands: x = [-10:.1:10]; y = [-10:.1:10]; plot3(x, y, x.^2 + 3*y) grid on In case it may

I'm trying to vectorize the following MATLAB operation: Given a column vector with indexes, I want a matrix with the same number of rows of the column and a fixed number of columns. The matrix is initialized with zeroes and contains ones in the locations specified by the indexes. Here is an example of the script I've already written: y = [1; 3; 2; 1; 3]; m = size(y, 1); % For loop yvec = zeros(m, 3); for i=1:m yvec(i, y(i)) = 1; end The desired result is: yvec = 1 0 0 0 0 1 0 1 0 1 0 0 0 0 1 Is it possible to achieve the same result without the for loop? I tried something like this: %
