R Programming: Create Two 2x3 Matrices and Perform Operations

R Programming: Matrix Exercise-5 with Solution

Write a R program to create two 2x3 matrix and add, subtract, multiply and divide the matrixes.

Sample Solution:

R Programming Code:

# Create the first 2x3 matrix with elements 1 to 6
m1 = matrix(c(1, 2, 3, 4, 5, 6), nrow = 2)

# Print a message indicating the following output is Matrix-1
print("Matrix-1:")

# Print the contents of the first matrix
print(m1)

# Create the second 2x3 matrix with elements 0, 1, 2, 3, 0, 2
m2 = matrix(c(0, 1, 2, 3, 0, 2), nrow = 2)

# Print a message indicating the following output is Matrix-2
print("Matrix-2:")

# Print the contents of the second matrix
print(m2)

# Perform element-wise addition of the two matrices
result = m1 + m2

# Print a message indicating the following output is the result of addition
print("Result of addition")

# Print the result of the matrix addition
print(result)

# Perform element-wise subtraction of the two matrices
result = m1 - m2

# Print a message indicating the following output is the result of subtraction
print("Result of subtraction")

# Print the result of the matrix subtraction
print(result)

# Perform element-wise multiplication of the two matrices
result = m1 * m2

# Print a message indicating the following output is the result of multiplication
print("Result of multiplication")

# Print the result of the matrix multiplication
print(result)

# Perform element-wise division of the two matrices
result = m1 / m2

# Print a message indicating the following output is the result of division
print("Result of division:")

# Print the result of the matrix division
print(result)

Output:

[1] "Matrix-1:"
     [,1] [,2] [,3]
[1,]    1    3    5
[2,]    2    4    6

Explanation:

• Create Matrix m1:
• A 2x3 matrix m1 is created with values 1 through 6.
• Print Matrix m1:
• The matrix m1 is printed along with the label "Matrix-1:".
• Create Matrix m2:
• A 2x3 matrix m2 is created with values 0, 1, 2, 3, 0, and 2.
• Print Matrix m2:
• The matrix m2 is printed along with the label "Matrix-2:".
• Add Matrices m1 and m2:
• The element-wise addition of matrices m1 and m2 is computed and the result is printed.
• Subtract Matrix m2 from m1:
• The element-wise subtraction of matrix m2 from matrix m1 is computed and the result is printed.
• Multiply Matrices m1 and m2:
• The element-wise multiplication of matrices m1 and m2 is computed and the result is printed.
• Divide Matrix m1 by m2:
• The element-wise division of matrix m1 by matrix m2 is computed and the result is printed.
