octave

In python one can use zip to loop multiple vectors or enumerate to get the current index of the looped vector like so one = ['A', 'B', 'C'] two = [1, 2, 3] for i, j in zip(one, two): print i, j for j, i in enumerate(one): print i, two[j] Gives >>> A 1 B 2 C 3 A 1 B 2 C 3 In MATLAB it's possible to do one = {'A' 'B' 'C'}; two = [1 2 3]; for i = 1:1:length(one) printf('%s %i\n', one{i}, two(i)); endfor j = 1; for i = one printf('%s %i\n', i{1}, two(j)); j = j + 1; endfor giving A 1 B 2 C 3 A 1 B 2 C 3 So is one of those two options the common way how one would do it in MATLAB, i. e. to loop

In C / C++ languages one can use macros or as called "per-processor directives" to instruct the compiler how the code should be read. The simple commands of #def , #ifdef , #ifndef , #else , #endif ... give the compiler the ability to check for Operating system, compiler and other environment information. I know Octave and Scilab are interpreted languages, but I'm wondering if is there any way to tell the interpreter to replaces parts of script while loading it? For example can I write a code which is commented based on Scilab syntax // and then instruct the interpreter to read them as Octave

I have two vectors, X of bases and N of exponents. I want to get the matrix of all values e = x n for each x in X and n in N . For example, the following input: X = [2 3 4]' N = [1 2 3] should produce: ans = [2 4 8; 3 9 27; 4 16 64] Is there a way to get this without looping (just like you can get all values of x×n by using the column by row product)? Use bsxfun : bsxfun(@power, X, N) This assumes that X is a column vector and N is a row vector. If you want to guarantee that, use the following syntax which is more robust: bsxfun(@power, X(:), N(:).') This is probably a bit sloppier than the

How can I resize x and y axis ? What I want, n more specific; 3900 | . | . | . | 60 | | 30 | |_____________________________ 0 60 120 180 ... 3600 What I have done ; a = [0:0.1:10000]; plot(a); What should I write so that resizing x and y axis is done as expected? EDIT: I do not want; | | | | | | | | | | 3900 | . | . | . | 60 | | 30 | |___________________________________________________________________ 0 60 120 180 ... 3600 Check the documentation: http://www.mathworks.com/help/techdoc/ref/axis.html axis([xmin xmax ymin ymax]) Another way: xlim([0 3600]) ylim([0 3900]) http://www.mathworks.com

I use octave 3.8.2 (with gnuplot) under Windows. I want to write "special character" in the axis labels of plots. The umlaut 'ä' and special character µ are displayed in the figure but not saved to the image file using print. Partly, I can use the TeX command: '\mu' instead of 'µ' but for umlauts '\"a' instead of 'ä' does not work. plot(1:10); %set (findall (gcf (), "-property", "interpreter"), "interpreter", "TeX") % does not work xlabel('Länge in µm'); ylabel('Breite in \mum'); print('umlaute.jpg', '-djpeg'); graphics_toolkit("gnuplot") and pngcairo or pdfcairo produce a better output.
