<｜begin▁of▁sentence｜>### Instruction:
As a Clinical Dietitian, imagine you have two sets of dietary intake data for two individuals. Individual A's intake includes 1 serving of protein and 2 servings of vegetables, while Individual B's intake includes 10 servings of protein and 20 servings of vegetables. How would you go about adjusting Individual A's dietary intake to match Individual B's intake, and what would the updated dietary intake for Individual A look like?
### Response:
from sympy import Matrix

# Initialize two matrices A and B
A = Matrix([[1, 2], [3, 4]])
B = Matrix([[10, 20], [30, 40]])

# In-place subtraction of matrix B from A
A.__isub__(B)

# Print the result
print('After in-place subtraction, A =')
print(A)
