I would like to create a loop that creates a different variable name after each iteration

Question

I would like to create a set of distinct variables in the form of e_1 , e_2 , e_3 ... The number of variables would depend on the value of k as shown below.

for i = 1:k

  "create variable" = e_"i";

end

I will then want to call these variables; hence, I would need another loop that would be able to assign the correct value to each variable created before, or pull something out of the variable.

Answer 1

One option would be to do something like this:

kk = 10;
for ii=1:kk
  eval(['e_' num2str(ii) '=[];'])
end

Answer 2

I got just the fix for you. Was just trying to do the same thing. Needed to be able to create an array with an infinate number of variables. Here's what I came up with. Well, I was adding 2 variables at a time, so it may be a little different than your version.

String[] parts;
String x = "";
String var = "";
int i = 0;
//to add variables
if(x.contains("-"){
 x+="-"+var;
}
else{
x+=""+var;
}

then to get them, u just use.

if(x.contains("-")){
parts = x.split("-");
while(i<parts.length){
  var=parts[i];
  i++;
 }
}
else if (x!=""){
var = x;
}

Changing the variables is a whole other story. I'll let your gifted mind figure that out. I don't need that part yet.

*hint, you're going to have to loop and put together the whole String back together with the new variables. Hope this helped. Felt like this was a new way of looking at it.
