You should probably go through the online tutorials for learning MATLAB. But I will give you an outline to get started:
tolerance = _____; % the tolerance to use for stopping condition
difference = _____; % an arbitrary number that is >= tolerance (so you get inside the while loop below)
n = 1; % the starting value of n
one_over_e = _____; % the intial estimate of 1/e (an expression involving n)
while( difference >= tolerance )
_____ % PUT CODE IN HERE TO INCREMENT n, calculate a new estimate, calculate the new difference, etc.
end
_____ % PUT CODE HERE TO PRINT RESULTS
You need to fill in the blanks
