octave 3.8.1 can't stop execution in gui command window

由 我的梦境 提交于 2021-02-18 09:53:29
问题 I'm running octave 3.8 with the gui in Ubuntu 14.04. I have an infinite loop somewhere in my program and it seems like the terminal doesn't respond to the typical keypresses to stop execution. (eg. Ctrl+C, Ctrl+Z) When I run programs in the terminal, I can just press Ctrl+C, but that doesn't seem to work here. What can I do to halt execution? 回答1: To stop a running command or script in octave GUI or prompt: Ctrl + C you will see: less -- (f)orward, (b)ack, (q)uit To abort (and close the GUI

问题 I am attempting to publish some Octave code as a PDF, however, I keep on getting the same error message: 'pdflatex' is not recognized as an internal or external command, operable program or batch file. I have also downloaded MikTex now but it still does work when I use the command options.format='pdf'; options.showCode = false; publish('document1.m',options) Why is this not working? 来源： https://stackoverflow.com/questions/61815611/pdflatex-to-convert-octave-code-into-pdf-documents

问题 I want to load a set of data that contains variables type string and float. But when I use textscan in octave, my data doesn't load. I got matrix 1x6 (i have 6 features), but in this matrix I got cells that contains nothing(cells that are 0x1). my code: filename='data1.txt'; fileID = fopen(filename,'r'); data = textscan(fileID,'%f %s %s %f %f %s','Delimiter',','); fclose(fileID); when I for example try data(1): >> data(1) ans = { [1,1] = [](0x1) } >> there is it there is my set Also my file

Update matrix, single column per row where row index is in vecor

由 拟墨画扇 提交于 2021-02-10 19:40:28
问题 Is there a way to update different column in each row of matrix, where row indices are stored in vector. Example mx = zeros(10,10); cols = [2 3 5 4 6 8 9 1 2 3]'; for i = 1:size(mx,1) mx(i,cols(i)) = 1; end mx produces 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 The question is, whether I can do it without the for loop? 回答1: You can
