Question

write matlab script

5. Use a for loop to sum the elements in x = [1 2 3 4 5] Check your answer with sum function 6. Use a while loop to sum the elements in x = [1 2 3 4 5] Check your answer with sum function

Answer 1

Matlab code:

5)Sum using for loop

//main code

x=[1,2,3,4,5];

y=0;

for n=1:length(x)

y=y+x(n);

end

//end of main code

y
y =
15

//main code

z=sum(x)

//end of main code
z =
15

As we can see the value of y and z are same.

y is calculated using for loop and z is calculated using sum function.

6)Sum using while loop

//main code

a=[1,2,3,4,5];

s=0;

i=1;

while i<=length(a)

s=s+arr(i);

i=i+1;

end

//end of main code

s
s =
15

//now we use sum function

//main code

z=sum(x)

//end of main code

z

z =
15

As we can see the value of s and z are same.

s is calculated using while loop and z is calculated using sum function.
