Write a R program to create a matrix taking a given vector of numbers as input. Display the matrix.

Sample Solution:

R Programming Code:

# Create a matrix with the numbers 1 to 16, arranged in 4 rows and filled by row
M = matrix(c(1:16), nrow = 4, byrow = TRUE)

# Print a message indicating the matrix being displayed
print("Original Matrix:")

# Print the matrix
print(M)

Output:

[1] "Original Matrix:"
     [,1] [,2] [,3] [,4]
[1,]    1    2    3    4
[2,]    5    6    7    8
[3,]    9   10   11   12
[4,]   13   14   15   16                   

Explanation:

• M = matrix(c(1:16), nrow = 4, byrow = TRUE):
• Creates a matrix M using the numbers 1 to 16.
• The matrix is arranged with 4 rows (nrow = 4).
• The byrow = TRUE argument specifies that the matrix should be filled by rows (i.e., from left to right across each row).
• print("Original Matrix:"):
• Prints the message "Original Matrix:" to indicate the start of the matrix output.
• print(M):
• Prints the matrix M to display its contents, showing a 4x4 matrix filled with numbers from 1 to 16 in row-major order.
