Problem Statement

A friend of mine runs a pharmacy.   He has a specialized function in his Dispensary application which receives a decimal value of currency and replaces it to a standard value.   This value is regulated by a government department.

Given a floating point value between   0.00   and   1.00,   rescale according to the following table:

Let's start with the solution:

  function y = rescale(x) 
	 
     L = [0,.06:.05:1.02];
     V = [.1,.18,.26,.32,.38,.44,.50,.54,.58,.62,.66,.70,.74,.78,.82,.86,.9,.94,.98,1];

     y = x; 
     for k=1:numel(x); 
        y(k) = V(sum(L<=x(k)));
     end;
  end;

   t=0:0.001:1;
   plot(t,rescale(t));
