Can't plot exponential function

clc;
X= (0:1:5);
Y=[2200*cos(9939.31*X)- 243.46*sin(9939.31*X)]*exp(-1100*X);
plot (X,Y)

I keep getting error on the function and not sure what I did wrong. Please help me find the error. Thank you

There are syntax issues with your code. Try the following code and compare it with your code to see the mistake

clc;
X= (0:1:5);
Y = (2200*cos(9939.31*X)-243.46*sin(9939.31*X)).*exp(-1100*X);
plot (X,Y)
