matrixA = rand(100,2)
matrixB = zeros(100,1)
a= 78.6
b = 90.6
c = 99.5
d = 156.1
   for i = 1:100
      if matrixA(i,2) <  0
      matrixB(i,1) = i/a*i
      else if matrixA(i,1) >=0 <= a
      matrixB(i,1) = b/c
          else if matrixA(i,1) > a <= b
          matrixB(i,1) = a/d*5
             else if matrixA(i,1) > c <=d
             matrixB(i,1) = a*d*c
                else if martixA(i,1) >d
                matrixB(i,1) = 78/b*d
            end
          end
       end
      end
     end
    end

I cant get the code to peruse through all the else if statements. It will only peruse the first else if statement then skip the rest.

Justin, almost there...

for i = 1:100
    if matrixA(i,2) <  0
        matrixB(i,1) = i/a*i
    elseif matrixA(i,1) >=0 && matrixA(i,1) <= a
        matrixB(i,1) = b/c
    elseif matrixA(i,1) > a && matrixA(i,1) <= b
        matrixB(i,1) = a/d*5
    elseif matrixA(i,1) > c && matrixA(i,1) <= d
        matrixB(i,1) = a*d*c
    elseif martixA(i,1) > d
        matrixB(i,1) = 78/b*d
    end
end
