Changing Variable Name during "While" loop

Hello,

I am writing with a "while" comment, and would like to change my variable name in each loop.

x = 1;
while x<=n
      if Choice_Accuracy(x,1) == 1
         Choice_RT_x = Choice_Input(x,1)
      else Choice_RT_x = 0
   end
x = x + 1:
end

Could someone tell me how I can Change the variable name "Choice_RT_x" to "Choice_RT_1", "Choice_RT_2", "..." with each loop? I know there are a lot of questions like these, but they are all with a "for" and I really don't understand it.

Thank you very much!

You can use the 'eval' function. Please see the following code:

x = 1;
while x<=n
      if Choice_Accuracy(x,1) == 1
         eval(['Choice_RT_' num2str(x) '= Choice_Input(x,1)']);
      else 
         eval(['Choice_RT_' num2str(x) ' = 0']);
   end
x = x + 1:
end

Hi,

it my help:

x = 1;
while x<=n
      if Choice_Accuracy(x,1) == 1
         eval(['Choice_RT_' num2str(x) '=Choice_Input(x,1);']);
      else eval(['Choice_RT_' num2str(x) '=0;'])
   end
x = x + 1;
end
