Chapter 10, Problem 10.1P

Expert Solution & Answer

To determine

To write:

The function that will receive a value for r and calculate and return the sum of the geometric series and if a second argument is passed to the function, then the function generates a random integer for n.

Answer to Problem 10.1P

Solution:

The function file is,

% MATLAB code to create a function that will receive a value for r and calculate and return the sum of the geometric series and if a second argument is passed to the function, then the function generates a random integer for n.

%function file

function sum = geomser(r, varargin)

%define the function geomser.

arg = nargin;

if arg == 2

%if arguments are two then it will generate proper sum.

n = varargin{1};

%if only second argument is present then it will take a random integer

%for n.

else

n = randi([5, 30]);

end

s = 1;

for j = 1:n

s = s + r.^j;

end

sum = s;

end

% end of function file

%The function file should be placed in the same folder.

Explanation of Solution

The formula for to calculate the sum of a geometric series is given as,

S=1+r+r2+r3+r4+...+rn

Substitute 3 for r and 5 for n in the above formula.

S=1+(3)+(3)2+(3)3+(3)4+(3)5=364

MATLAB Code:

% MATLAB code to create a function that will receive a value for r and calculate and return the sum of the geometric series and if a second argument is passed to the function, then the function generates a random integer for n.

%function file

function sum = geomser(r, varargin)

end

s = 1;

for j = 1:n

s = s + r.^j;

end
