Which MATLAB function is used to calculate the inverse of a matrix A?

Ainverse(A)
Binvert(A)
Cinv(A)
Dmatrixinv(A)
Step-by-Step Solution
Solution:

  1. Step 1: Recall MATLAB matrix inverse function

    The standard MATLAB function to compute the inverse of a matrix is inv().

  2. Step 2: Verify function names

    Functions like inverse(), invert(), or matrixinv() do not exist in MATLAB.

  3. Final Answer:

    inv(A) -> Option C

  4. Quick Check:

    Inverse function = inv(A) [OK]
Quick Trick: Use inv(A) to find matrix inverse in MATLAB [OK]
Common Mistakes:
  • Using non-existent functions like inverse()
  • Confusing inv() with transpose functions
  • Trying to invert non-square matrices
