Hello to everybody,
I have a problem with a particular algorithm that performs a multi-objective optimization.
When I try to select a certain number of columns using two parameters in the algorithm this error appears: "Undefined operator '+' for input arguments of type 'table'", but when I try to do the same thing with 2 normal passages on the command window it works.
Could someone help me?
There are some pictures to understand what I meana.jpg

I thought that was an elegant way use this kind of variable.
I have changed my script defining the variables for each function and it seems to work.
Thank you, I was going crazy

try this:
i=V+M+1;
a= table2array(population(:,i))
if all(a(:)==0)
...
end
