%% Input
PlayerLevel = 1:100;
MonsterLevel = 1:85;
%% Calculations
% Create a repeated matrix:
mPlayerLevel = repmat(PlayerLevel, length(MonsterLevel), 1);
mMonsterLevel = repmat(MonsterLevel, length(PlayerLevel), 1)';
% Minimum amount of experience penalty:
minEXPMulti = 0.01;
% There's a safe zone between player level and monster level where no
% experience penalty is applied:
SafeZone = floor(3 + mPlayerLevel/16);
% Any additional level difference in excess of this safe range is the
% effective level difference:
EffectiveDifference = max(abs(mPlayerLevel - mMonsterLevel) - SafeZone, 0);
% If the effective difference is negative that implies the player is inside
% the safe zone. Therefore only values =>0 are relevant.
% If the player level is outside the safe zone a multiplier on monsters
% experience takes effect, reducing the amount by:
XPMultiplier = max(((mPlayerLevel + 5) ./ ...
(mPlayerLevel + 5 + EffectiveDifference.^2.5)).^1.5, minEXPMulti);
