Octave sample programs

Geometric Signal Theory This section follows Chapter 5 of the text. Note the use of. If x is a row- or column-vector, then length x gives the number of elements.

For matrices, length returns the greater of the number of rows or columns. When collinearity is close to 1, they are nearly collinear. Orthogonal Basis Computation Matlab and Octave have a function orth which will compute an orthonormal basis for a space given any set of vectors which span the space.

In Matlab, e. That is, yw is the optimal least-squares approximation to y in the space spanned by v1 and v2 w1 and w2. In other words, norm yerror is less than or equal to norm y-yw2 for any other vector yw2 made using a linear combination of v1 and v2. How will I get stage1 curve in orange color and stage2 curve in blue color in the same plot to know which stage has which displ values?

I am new to Octave. Would like to plot the rear suspension in 3D. I am a 61 year old. Please need help. Do you have the mathematical equation of the same? If yes, plug it in, as per the above examples. Hi Anil, Firstly thank you for this post, I have a doubt, regarding the syntax, as i am facing an error Octave 6.

At the Octave prompt, you can recall, edit, and reissue previous commands using Emacs- or vi-style editing commands. The default keybindings use Emacs-style commands. For example, to recall the previous command, press Control-p written C-p for short. Doing this will normally bring back the previous line of input.

C-n will bring up the next line of input, C-b will move the cursor backward on the line, C-f will move the cursor forward on the line, etc. A complete description of the command line editing capability is given in this manual, see Command Line Editing.

Octave has an extensive help facility. The same documentation that is available in printed form is also available from the Octave prompt, because both forms of the documentation are created from the same input file. In order to get good help you first need to know the name of the command that you want to use. The name of this function may not always be obvious, but a good place to start is to type help --list.

This will show you all the operators, keywords, built-in functions, and loadable functions available in the current session of Octave. An alternative is to search the documentation using the lookfor function described in Getting Help. Once you know the name of the function you wish to use, you can get more help on the function by simply including the name as an argument to help.
