Question

Use Matlab

Q1. Write a code to determine if a number is divisible by 2 Q2. Write a function to calculate the average of a vector with one input argument and find the average of the following vectors [1 2 3 4] b. [1 2 3 4 5 6 a.

Answer 1

Solution:

1.a number is divisible by 2 or not

%%---------- Code Starts here-------------%%

prompt = 'What is the original value? ';
x = input(prompt);
if rem(x,2)==0
disp('divisible by 2')
else
disp('not divisible by 2')
end
%%------------------- END ---------------------%%

2.average of vector elements

(a) x=[1 2 3 4];

%%--------- Code start here -----------%%

x=[1 2 3 4];
add=0;
for i=1:4
add=add+x(i);
end
average =add/4

%%------------------ END --------------------%%

(b)x=[1 2 3 4 5 6];

%%------------ Code starts here ----------------%%

x=[1 2 3 4 5 6];
add=0;
for i=1:4
add=add+x(i);
end
average =add/6

%%------------------- END ------------------------%%
