MATLAB: How to draw the power series in matlab

matlab plot

I want to draw the series without using cycle such as "for".The general term of the series is 1/n!, so what should I do?

%range of n=25
n = 0:25;
y = cumsum(1./factorial(n));
% plot results
plot(n,y,'r')

There is no 'x' in your expression inside symsum(). I guess you are tyring to plot taylor series of exp(x). Try this

syms n x
F = symsum(x^n/factorial(n),n,0,5);
fplot(F, [0 2])

help taylor

Best wishes

Torsten.
