Hi, My histogram is not showing what I would like can I get some help please?

This is my code is running and making histogram as well, but not at the right place.

A=input('How many tossing would you like to do? ')
x= rand(A,1);
    if(x<0.5),
    toss = -1; %Head
    else
    toss = 1;  %Tail
    end
    hist(x,-2:2)

Asyou can se one bar is at 0 and the other is at 1. I would like if Heads been shown at -1 and Tails at 1.

Thank you for any help.

The problem is that you are not storing the answers/toss.

A=input('How many tossing would you like to do? ')
x= rand(A,1);
toss = nan(A,1);
for i=1:length(x)
    if x(i)<0.5
        toss(i) = -1; %Head
    elseif x(i)>=0.5
        toss(i) = 1;  %Tail
    else
        disp('Error...')
    end
end
histogram(toss)

Edit: If you want it more neat

A=input('How many tossing would you like to do? ')
x= rand(A,1);
above = x < 0.5;
x(above)=-1;
x(~above)=1;
histogram(toss)

Thank you very much for help!

Or even more compact (though perhaps a little harder to understand):

numTosses = 100000
tosses = 2 * (rand(1, numTosses) < 0.5) - 1;
histogram(tosses)

Its ok I used the first one. I need write an essay about my codes so I need at least understand a bit. but thanx for the answare.
