Suppose you want a utility (such as matrixTeX.m ) to be visible to every octave session. 1. Select a suitable folder to keep your local ...

On a recent exam, I asked students for suggestions on how to test for equality of two floating point numbers. Loren Shure and  Mike Crou...

GNU Octave has a very capable plotting system (which is transitioning away from gnuplot as its backend, even as we "speak"). Quit...

Consider a simple Matlab/Octave exercise. I have an N by 2 vector  x . Thus, x(i,1) and x(i,2) are the entries of the i-th row. Say I w...

A very nice blog on making journal quality graphs by extensively using handles at Loren and the Art of Matlab. As a side note, the actua...

As many of you who use Matlab might know, Cleve Moler was a professor of math and computer science at a bunch of universities (including M...

Suppose you are given a bunch of points in the form of a vector x (between "a" and "b") and an accompanying density fun...

In a previous pos t, I mentioned subfunctions in Octave and Matlab. Nested functions are an interesting new beast. I can see situations ...

Consider a simple example. If x and y are two vectors of the same size, one obvious way of writing them to file is: n  = 1e5; x  = 1:n; ...
