Re: Constant errors although the program is correct

[Abhinav Dronamraju]

Also, the name of the function you wrote is func and you're calling difuncao. I would advice you to follow these points below.

1. Name the file as func.m since your function name is func.

2. Go to the directory in which that file is and execute it using exec func.m

3. Then call the function with any x0 you want. 

I believe this should work properly.

Could you elaborate your problem a little. I wrote the same script as you did and it worked fine for me. My advice is to check the following points.

1. Is your file name and function same ?

2. Did you execute your function file using exec func.m before trying to use it in command window ?

hi, i wrote this script: function y = func(x0)
                                y = 49890/10000 + sin(x0) - x0.^2
                                end
it's a simple script but when I run the program it gives me multiple errors
and this happens in all the programs that you write. This is normal? is that
it gives error but when I call the function in the command window and assign
it to the variable it gives me the result .... Another question: how do I
call a function inside a script? Thank you!

(errors like this:
>> difuncao
error: 'x0' undefined near line 2 column 12
error: evaluating argument list element number 1
error: called from:
error:   /Users/monteirojp/Documents/FCUL - MATAPL/2º
ano/NUMERICA/exercicios em octave/difuncao.m at line 2, column 5
>>
)
