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
  • elseif is one word.
  • Two conditions (e.g. range of values) need to be combined with a logical &&
