# R Programming: Extract the submatrix whose rows have column value > 7 from a given matrix

## R Programming: Matrix Exercise-7 with Solution

Write a R program to extract the submatrix whose rows have column value > 7 from a given matrix.

**Sample Solution:**

**R Programming Code:**

```
row_names = c("row1", "row2", "row3", "row4")
col_names = c("col1", "col2", "col3", "col4")
M = matrix(c(1:16), nrow = 4, byrow = TRUE, dimnames = list(row_names, col_names))
print("Original Matrix:")
print(M)
result = M[M[,3] > 7,]
print("New submatrix:")
print(result)
```

Sample Output:

[1] "Original Matrix:" col1 col2 col3 col4 row1 1 2 3 4 row2 5 6 7 8 row3 9 10 11 12 row4 13 14 15 16 [1] "New submatrix:" col1 col2 col3 col4 row3 9 10 11 12 row4 13 14 15 16
