Writing full MATLAB code is not usual in this forum. If your MATLAB skills are too low to complete the program, do this in another programming language you are more familiar with.

Use the randi function. It's so simple it's hard to guide you without doing the whole thing for you but I'll try:
numberOfRolls = 100;
numberOfDice = 6;
distribution = zeros(6,1);
for roll = 1 : numberOfRolls
diceValues = randi(6,[numberOfDice 1]);
% Accumulate into the distribution.
for die = 1 : numberOfDice
distribution(diceValues(die)) = % You figure it out.
end
end
% Plot it.
bar(% You figure it out.);

Do you need me to spell out the needed adaptations?
numberOfDice = 4;
because you wanted 4 dice, not 6, and
distribution(diceValues(die)) = distribution(diceValues(die)) + 1;
to store your results for this roll, and
bar(distribution);
to do the plotting of the distribution. Now you have everything. Certainly it can't be that tough to figure out now! I think you really need to at least scan through the "Getting started" section because the code I posted was very simple, basic, and self explanatory and should have been easily understood by anyone who has done any programming at all.
