I have a nested if statement which works as it is supposed to until the last iteration.

Does anyone know why it is not multiplying the last value by -1?

`w = x_0 % zero vector `

k = 0 % zero value

i=1 % initial value for count

j=-1 % coefficient

for i = 1:n if Raw_Data(i,2) == Raw_Data (i,3) fprintf ('ERROR!!!!!) else if Raw_Data(i,3) == val w(i,1) = Raw_Data(i,4) else if Raw_Data(i,2) == val w(i,1) = j* Raw_Data(i,4) % Rationalisation Not Working

else w(i,1)= j* Raw_Data(i,4) end end end i=i+1 end
