How to check the length/number of characters of a string inputted by a user in Octave?

Have seen people ask about length of an input but never relative to Octave.

I would like to test the length of the user's response to an input command. I have already tried this method:

x=input('enter a set of numbers')
length(x)

This doesn't work. Entering "2345" will give you a length of 1, and entering "abcdefg" gives you an "undefined variable: abcdefg" error.

I have also tried:

x="blahblah"
length(x)

This gives the proper length, but I'm trying to test the length when x is equal to an input from a user, not predefined text.

For example, If the user inputs 5 numbers or 5 characters, I want the length to to be 5.

This length must also be usable in a vector. For example:

vector=[1,2,5,7,length(x),4]

How do I test the amount of CHARACTERS (letters or numbers) in the user's response?

Solution

  • In octav you should write the following:

    x=input('enter a set of numbers', 's');

    Add 's' to specify that the input is string, or input the string by"", for example "blahblah", without any change to your code. The other part of the code should work without any problem.
