Hi,
Below are the implementations for the factorial and the power functions. You can store the values from both the functions in an array at each step and then plot these on the same plot using the "plot" function twice. To plot on the same figure, you need to use the "hold" command.
function result = numFactorial(number)
if(number == 0 || number == 1)
result = 1;
else
result = 1;
for index = 1: number
result = result* index;
end
end
end
function [result] = pow(number, numPower)
if(numPower == 1)
result = number;
elseif(rem(numPower, 2) ~= 0)
%a = getpowby2(number, (numPower-1)/2);
a = pow(number,(numPower-1)/2);
result = a*a*number;
else
%a = getpowby2(number, numPower/2);
a = pow(number, numPower/2);
result = a*a;
end
end

This may help you get started
doc hold
doc factorial
doc power
n = 5;
x = 2;
vector = 1:n;
plot(factorial(vector));
hold on
plot(power(x,vector));
% or the 2 plot commands can be integrated into 1 like below
% plot(vector,factorial(vector),vector,power(x,vector));
