Re: Constant errors although the program is correct

[Abhinav Dronamraju]

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
