A?Which MATLAB command correctly computes the null space of a matrix A?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall MATLAB functions for matrix properties
null(A)returns the null space vectors of matrix A.Step 2: Identify incorrect options
rank(A)gives rank,det(A)gives determinant,inv(A)gives inverse if it exists.Final Answer:
null(A) -> Option CQuick Check:
null space = null(A) [OK]
Quick Trick: Use null(A) to find null space vectors [OK]
Common Mistakes:
- Using rank(A) instead of null(A)
- Confusing determinant with null space
- Trying to invert a non-square matrix
