Loading Data

I'm a complete noob here, but I'm having trouble loading data into octave using a script. I can do it from the command line no problem by doing the following:
load ('torque.txt'); x = torque; plot (x); but within a script it pukes when trying to assign x. Any ideas? BTW, I'm using Windows and the latest version of Octave. Thanks, Tweed |

Thanks, This sounds like a problem between global scope and local scope. try saying: global torque kensmith99@... _______________________________________________ Help-octave mailing list Help-octave@... https://www.cae.wisc.edu/mailman/listinfo/help-octave |

If load is invoked using the functional form load ("-text", "file.txt", "a") then the OPTIONS, FILE, and variable name arguments (V1, ...) must be specified as character strings. What you have appears to be the function form. Perhaps it isn't parsed the same when it is read from a file instead of from the terminal. Try doing it exactly like the example line and see what happens. Thanks for the help, but I tried that method already. When I use that I get the following error message: error: load: empty name keyword or no data found in file The file I'm trying to load is an array of floating point numbers in text format... 0.0000 7.4533 7.6765 8.6432 etc... I can load it in Matlab or the Octave command window without any trouble. |

Okay, I figured out what my problem was. I was trying to use the path and filename together in the load command. I should have been using the path command to set the path first. path = 'C:\Program Files\Octave\Alan'; load ("TorqueArray.txt") x = TorqueArray; plot (x); Tweed |

It's difficult to say whether you've found a bug that should be fixed since I don't think you have yet provided enough information for someone to actually reproduce the problem you're having. Can you give a complete example (data file, preferably small) and the *exact* functions required and the commands you typed so that someone might be able to reproduce the problem you had?

If you use double quotes instead, the first statement will not work.

If you use double quotes instead, the > first statement will not work. #2 ('\\') doesn't work for me from command line. Funny though, it does work with double quotes. I suppose there is some interaction with Windows' method of interpreting commands, but I can't get my mind around it this time of the morning.
