Error: Unbalanced or unexpected parenthesis or bracket

8 views (last 30 days)
The matlab show this error "Error: Unbalanced or unexpected parenthesis or bracket." in this part of the code:
%**************************************
nome = '105.txt';
[pathstr, name, ext] = fileparts(nome);
load(nome);
x=eval([name '(:,1)']);
y=eval([name '(:,2)']);
z=eval([name '(:,3)']);
%*************************************
---------------------------------------------------------------
105.txt contains 3 columns with several rows...
But on my friend's pc don't show this error... I have a Asus x64, with windows 10 and Matlab R2014b...
I think the problem is not from the code as it was functional on other pc's. I think it has to do with my compiler, but I don't know how to fix it ...
Already installed the version Matlab 6.5 R13, but the same error appears ...
What may be the source of this error?

"I think the problem is not from the code ..."
In fact the problem is very badly designed code that relies on complex eval to generate invalid variable names. That code should be thrown away, it is never going to be reliable or efficient.

I think name is variable, it's simply (there is no need for eval):
x = name(:,1);
y = name(:,2);
z = name(:,3);

The "name" came from of "[pathstr, name, ext] = fileparts(nome);"
The previous code is:
%********************************************
nome = '105.txt';
[pathstr, name, ext] = fileparts(nome);
load(nome);
x=eval([name '(:,1)']);
y=eval([name '(:,2)']);
z=eval([name '(:,3)']);
%***********************************************
105.txt contains 3 columns with several rows...
