octave

I want to calculate some matrix algorithms using the GNU Octave library. I know I can use C/C++ API of Octave for basic use. However the method I want to use is not in the default packages of Octave. So how to use Octave's control package in the C/C++ program? Appleman1234 Something like this embed.cpp #include <iostream> #include <octave/octave.h> int main(int argc,char* argv) { int embedded; octave_main(argc,argv,embedded=0); return embedded; } Then mkoctfile embed.cpp --link-stand-alone -o embed in order to make a standalone executable. To call octave functions whether they are provided by

The Octave documentation on this subject is both intimidating and sparse. I did not know where else to document the solution I found, so I am posting here. I apologize if that's inappropriate, but I want to help the next guy. The following solution is for a simple windows distributable. Use Case: A solution is developed in Octave 3.2.4, and needs to be distributed to end-users with few computer skills. Installing and explaining Octave is impossible, the solution must be "one-click" or "brain-dead-simple." Known Issues: imread fails in 3.2.4 because file_in_path.m is wrong. You will need to

I'm creating a sweep / chirp signal using matlab / octave and my ending signal seems to be ending at the wrong frequency. How can I fix it so that the signal ends at the correct frequency. PS: I can't use the chirp command in octave because I'm creating a chirp / sweep signal using a specific equation. Example code with simple equation. and plot of problem %test sweep / chirp clear all,clc freq1=20; %start freq freq2=200; %end freq fs=44100; dur=1; %duration of signal in seconds t = linspace(0,2*pi,fs*dur); f=freq1:(freq2-freq1)/length(t):freq2-(freq2-freq1)/length(t); %20:(200-20)/lenght(t)

Having a vector x and I have to add an element ( newElem ) . Is there any difference between - x(end+1) = newElem; and x = [x newElem]; ? ThijsW x(end+1) = newElem is a bit more robust. x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem , however, works for both row- and column-vectors. In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element,
