MATLAB: How to reference each element of a column vector in an if statement

communicationembedded matlab functionfor loopfrequencyfunctionfunctionshelphomeworkif statementloopsmatlab functionmatricesmatrixmatrix arrayscriptvectorvectorizationvectorswhile loopworkspace

I need to get AmountWon to reflect each element in the column vector spin. Everytime this runs I get AmountWon = 250000 because it is adding all the Spin values in the Spin vector.
For example, I want AmountWon to be different for each of the 10 different spin values… this could be stored in another variable x that replaces the value in each row by the amount won, if any.
x = zeros(11,10)
Slotrounds = 10
for  j = 1:SlotRounds
Spin(1,:) = rand(1,10) %generates a 1x10 column vector of rand. numbers
    for jj = 1:SlotRounds %a compares probability to winnings
        if Spin <= .99999
        AmountWon = 250000
        elseif Spin <= .99985
        AmountWon = 100000
        elseif Spin <= .99950
        AmountWon = 40000
        elseif Spin <= .99500
        AmountWon = 5000
        elseif Spin <= .93000
        AmountWon = 500
        else
        AmountWon = 0;
        end
    end
        
        x = %I want the x values to change in each row as the loop progresses
        
end

Hi Brian,
You need to use subscripts to index the Spin variable, as well as x. For example, 
if Spin(jj) <= .99999
    AmountWon(jj) = 250000
end
for x, 
    x(j,:) = AmountWon
Oh, there's a logic problem too. You're not testing if the Spin is between two values, just if it's less-than. So the first if statement almost always meets the condition. I think you want something more like:
x = zeros(11,10)
SlotRounds = 10
for  j = 1:SlotRounds
Spin(1,:) = rand(1,10) %generates a 1x10 column vector of rand. numbers
    for jj = 1:SlotRounds %a compares probability to winnings
        if (Spin(jj) <= .99999) & (Spin(jj) > .99999)
        AmountWon(jj) = 250000
        elseif Spin(jj) <= .99985 & (Spin(jj) > .99950)
        AmountWon(jj) = 100000
        elseif Spin(jj) <= .99950 & (Spin(jj) > .99500)
        AmountWon(jj) = 40000
        elseif Spin(jj) <= .99500 & (Spin(jj) > .93000)
        AmountWon(jj) = 5000
        elseif Spin(jj) <= .93000 & (Spin(jj) > .90000) %made up this lower limit
        AmountWon(jj) = 500
        else
        AmountWon(jj) = 0;
        end
    end        
        x(j,:) = AmountWon %I want the x values to change in each row as the loop progresses
        
end
