Hey,
The factorial of a number is calculated as
F(n) = (n-1)*(n-2)*(n-3)…….1 and F(0) = 1 always;
So we start from the right most side like F(p) where p = 1 initially and keep incrementing the value of p till n; The resultant value is your answer. I have written the function with variable n. replace n with any integer to get its factorial number;
Attaching the code for your reference.
function fact = factorial(n)
fact = 1; %base case, for F(0);
for i = 1:n %looping through values from 1 : n to multiply each value;
fact = fact*i; %multiplying with our previous values.
end
end
The fact will have your desired factorial of the integer you called function with.

okh so we are intresting in to finding the value of 7 factorial
programming:-
%calculation of factorial
n=7;
factvalue=1;
for i=1:7
factvalue=factvalue*i
end

its obvious !because the notation of factorial are denoted by n!
here we are finding the value of n! where n=7.
thats why we assinginf here n=7

So if I coded
%calculation of factorial
n=7;
factvalue=1;
for i=1:9
factvalue=factvalue*i
end
then afterwards factvalue would hold n! = 7! ? Or would it hold 9! ? Where is the connection between the value of n and the value calculated?

I made it for 10! but you can change 10 by any value
n=1; i=1;
while i<=10
n=n*i;
i=i+1;
fprintf('n=%d\n')
end

What is the point of printing a bunch of instances of "n=" repeatedly to console? Why is anything printed in the loop? Why use a while loop instead of a for loop?
What's wrong with
n = 10; % isolate the parameter
result = 1;
for k = 1:n
result = result*k;
end
result
... or just
result = prod(1:n)
... or, you know
result = factorial(n)

n=input('n=')
if n>=0&&n==fix(n)
f=1;
for i=2:n
f=f*1;
end
else
disp('ererr')
end
f

hecho de función = factorial(n)
hecho = 1; % caso base, para F(0);
for i = 1:n %recorriendo valores de 1:n para multiplicar cada valor;
hecho = hecho*i; %multiplicando con nuestros valores anteriores.
fin
fin hecho = 1; % caso base, para F(0); for i = 1:n %recorriendo valores de 1:n para multiplicar cada valor; hecho = hecho*i; %multiplicando con nuestros valores anteriores. finfin
