Issue with plotting. I put it in a vector but it returns a scalar once it goes through the calculation

Hi everyone

I wanted to plot this program. My N ranges from 1 to 60 and the function is set below it. However it only runs when N=60. Like i don't get a vector from er

%%%%%%%%%%%

x = 10;

N = [1:60]

sumN = x.^N/factorial(N);

er =abs(sumN-exp(x))/exp(x);

plot(N,er,'*')

在 MATLAB Online 中打开

Add a dot before the division symbol in the third line for element-wise division:

x = 10; 
N = [1:60]
sumN = x.^N./factorial(N);
er =abs(sumN-exp(x))/exp(x);
plot(N,er,'*')
