Hi,

I'm new to Matlab and am having trouble getting the following bit of script to work:

for i = 1:240;
    if shape1_win(i)==1 & shape1_loss(i)==1 & button_pressed(i)==1 | shape2_win(i)==1 & shape2_loss(i)==1 & button_pressed(i)==2;
        choose_both(i)=1;
    else
        choose_both(i)=0;
    end
end

The script is for a task in which participants have to choose a shape that can have a win, a loss, or both. What I want to do is create a new variable listing all the times participants chose a shape that had both a win and a loss. The shape variables are all 240x1 double type variables.

Every time I try to run this bit, I get an error saying there are not enough input arguments (starting on line 2). I'm probably missing something very obvious, could someone explain to me how to fix this?

How you are running this code?

Are shape1_win, shape1_loss, button_pressed, shape2_win, etc variables or functions? And is that actually 'line 2'? If it is and they are variables the error doesn't make sense as the only functions being called are & and |
