MATLAB

Question 1.

Given a vector x, write a script to create a vector v, which consists of the indices of all the

elements in vector x are greater than 3.

Question 2.

The sum of geometric series is written as

1 + 1/2+1/4+1/8+1/16+ …..

Write a function to find the sum of the geometric series, which receive the number of term n as

input argument

Solution

1.)

MATLAB CODE :

d=length(x);

v=zeros(1,d);

n=0;

for k=1:d

if(x(k)>3)

   n=n+1;

v(n)=k;

   end

end

v=v(1:n)

2.)

code for sum of geometric series:

MATLAB CODE :

sum=0;

for k=1:n

sum=sum+(1/2)^(k-1);

end

sum
