How to plot e^(-2n)

How would you actually plot e^(-2n) in Matlab?

Answer 1

[Stephen23]

f = @(x)exp(-2*x);
fplot(f)

Answer 2

[Jon]

Assign a vector of equally space values over the range of interest to the variable n

Assign a value y to a MATLAB expression that evaluates e^(-2n), check out the documentation for exp (type doc exp on the command line)

Use the plot command to plot y vs n check out the documentation for the plot command (type doc plot on the command line)

If you need to learn the basics of MATLAB I suggest the MATLAB On - Ramp training https://www.mathworks.com/learn/tutorials/matlab-onramp.html
