Question

Prepare a MATLAB program (script file) that allows a user to enter two 4-element vectors and scalar values to perform different mathematical (exponentiation, multiplication, and subtraction) operations on the elements within the originally entered vectors Moreover, the program also performs addition, dot product and element-wise multiplication of the two vectors.

Answer 1

MATLAB CODE

clc;
V1=input('Enter 4-element Vector 1 : ');
V2=input('Enter 4-element Vector 2 : ');
S=input('Enter Scaler : ');
%% exponentiation
disp('Vectors After exponentiation is ');
V1_exp=S.^V1
V2_exp=S.^V2
%% Multiplication
disp('Vectors After Multiplication is ');
V1_Mul=S.*V1
V2_Mul=S.*V2
%% Subtraction
disp('Vectors After Subtraction is ');
V1_Sub=V1-S
V2_Sub=V2-S
%% Vector Addition
disp('Vectors After Addition of Both Vectors is ');
V_Add=V1+V2
%% Vector Multiplication
disp('Vectors After Multiplication of Both Vectors is ');
V_Mul=V1.*V2
%% Dot Product
disp('Vectors After Dot Product of Both Vectors is ');
V_Dot=dot(V1,V2)

Results:

Enter 4-element Vector 1 : [4 1 3 1]
Enter 4-element Vector 2 : [4 5 1 6]
Enter Scaler : 4
