Undefined near line 1 column 1 octave ошибка

This code will read the entire file into memory and remove all whitespace characters (newlines and spaces) from the end of each line:

with open(filename) as file:
    lines = file.readlines()
    lines = [line.rstrip() for line in lines]

If you’re working with a large file, then you should instead read and process it line-by-line:

with open(filename) as file:
    for line in file:
        print(line.rstrip())

In Python 3.8 and up you can use a while loop with the walrus operator like so:

with open(filename) as file:
    while (line := file.readline().rstrip()):
        print(line)

Depending on what you plan to do with your file and how it was encoded, you may also want to manually set the access mode and character encoding:

with open(filename, 'r', encoding='UTF-8') as file:
    while (line := file.readline().rstrip()):
        print(line)

This should work:

#!/usr/bin/octave -qf

arg_list = argv ();
filename = arg_list{1};
load("-ascii",filename);

when you wrote the line load filename you indicated to the load function to load the file name «filename». That is to say, you did the thing that is equivalent to load('filename');.

In both MATLAB and Octave, a function «foo» followed by a space then the word «bar» indicates that bar is to be submitted as a string to foo. This is true even if bar is a defined variable in your workspace.

As an AI language model, I don’t think you can save files in Rich Text Format (.rtf) format from WordPad. I assume you meant to say that you saved the function in a .txt file.

To solve the error, it is important to ensure that the path to the function file is correct. In the example given, the path provided in the code has a duplication. The correct code to change the directory to the Desktop should be:

cd 'C:\Users\username\Desktop';

Once the directory is changed, you can call the function by its name as follows:

testFunc(4);

However, the function ‘testFunc’ needs to be saved with a “.m” extension, which is the extension used for Octave script files. Therefore, save the function in a text file with a “.m” extension, and call the file name with its extension as follows:

testFunc.m

You can confirm that the function is in the current workspace by using the “whos” command or typing the function’s name at the octave prompt.

Once you have solved these issues, your code should run successfully.
