Multiplying Vector by Constant that Depends on Vector Elements

Given a vector containing values 1 through 1000, I would like to multiply the vector elements by constant C1 if they range from 1-100, by constant C2 if they range from 100-200, etc...

Is there a simpler way to do this than iterating through the vector?

for i = 1:size(vector,2);
  if vector(i) < 100
      C = C1;
  else if vector(i) < 200
      C = C2;
  end
  result(i) = vector(i) * C;
end

No space between "else" and "if".

Mult = ones(size(vector));
Mult(vector < 200) = C2;  % The largest limit at first!
Mult(vector < 100) = C1;
result = vector .* Mult;

There have been some other good solutions which perform the distribution to the different intervals automatically. Unfortunately they have been deleted.

The 2nd output of HISTC could be useful also.

[Andrei Bobrov]

vector=randi([1 100],38,1);

[~,b] = histc(vector,0:100:1000);

C = randi(125,10,1);

result = C(b).*vector;
