Is this correct
m=0
for m=0:1200
x=sum(1/factorial(m))
end

No, because you need to subscript ‘m’ and sum ‘x’ in each iteration.
However you do not need the loop:
m=0:1200;
x=sum(1./factorial(m))

No, you need to increment m with each step and add each partial sum.
This is what you need:
x= 0
for m = 0:1200
x = x + 1/factorial(m(i))
end

why x if there is no x in the equation

x is just the variable that will store that whole summation
