Octave Parse Error Syntax Error

you have typed. For example, if you misspell a keyword, octave:13> function y = f (x) y = x***2; endfunction Octave will respond immediately with a message like this: parse octave undefined near line 1 column 1 error: syntax error >>> function y = f (x) y = x***2; endfunction
Octave Function Undefined
^ For most parse errors, Octave uses a caret (‘^’) to mark the point on the line where it octave function argument undefined was unable to make sense of your input. In this case, Octave generated an error message because the keyword for exponentiation (**) was misspelled. It marked the error at the third ‘*’
Syntax Error In Octave
because the code leading up to this was correct but the final ‘*’ was not understood. Another class of error message occurs at evaluation time. These errors are called run-time errors, or sometimes evaluation errors, because they occur when your program is being run, or evaluated. For example, if after correcting the mistake in the previous function definition, you type octave:13> f () Octave will syntax error end octave respond with error: `x' undefined near line 1 column 24 error: called from: error: f at line 1, column 22 This error message has several parts, and gives quite a bit of information to help you locate the source of the error. The messages are generated from the point of the innermost error, and provide a traceback of enclosing expressions and function calls. In the example above, the first line indicates that a variable named ‘x’ was found to be undefined near line 1 and column 24 of some function or expression. For errors occurring within functions, lines are counted from the beginning of the file containing the function definition. For errors occurring outside of an enclosing function, the line number indicates the input line number, which is usually displayed in the primary prompt string. The second and third lines of the error message indicate that the error occurred within the function f. If the function f had been called from within another function, for example, g, the list of errors would have ended with one more line: error: g at line 1, column 17 These lists of function calls make it fairl

You must be using one of the 3.2.X, the last of which is more than 3 years old. If you are using any of the 3.4.X (which was released more than 2 years ago) or later, it will work fine. –carandraug Jun 23 '13 at 16:43 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted You are using an old version of Octave which does not support ~ for return-value dismissal. You should upgrade your octave version to at least 3.4.0 (released more than 2 years ago) for that feature. Alternatively, you can work around it with: % don't care for value of TMP [ TMP, ix ] = sort(S1); ... [ TMP, ix ] = sort(S2); You must using an Octave from the 3.2.X series or ol

For example, I open Kate, or any other editor and type: Code: % Test file disp('This is a test') I save the file as testfile, and this is the result I get when I try to run it: Code: octave:1> testfile error: `testfile' undefined near line 1 column 1 Adv Reply May 7th, 2009 #2 Gilabuugs View Profile View Forum Posts Private Message 5 Cups of Ubuntu Join Date Jan 2008 Beans 23 Re: Octave 3.0 - Can't run .m files PHP Code: %testfile
