hi i'm new and learning about genetic algorithm sample codes
this is part of the code:
for p=1:popsize
for n=1:nd
r=rand;
if r<pm
new(p,n)=a*old(p,n)*rand;
else
new(p,n)=old(p,n);
end
end
end
i can't find any old(p,n) function, but it still can run. is old a function provided by the matlab? if so, is there a link to learn about it?
thank you

old is not the name of a Matlab function. Maybe you have a variable named old
What does
which old
return?

"[...] old should be in this same file right?" No, typically not. Only if ymutr1 is a local or nested function.
The code you showed in a previous comment is that the only content of a file named, ymutr1.m? If so, how did you make this function run? Somewhere there is a call like
out = ymutr1( first_input, second_input, x3, x4, x5 )
in another function or in a script or in the command window. The names of the arguments doesn't matter. See function, Declare function name, inputs, and outputs. old will take the value of first_input.
How did you call ymutr1?
