Hi @KIRAN Sajjanshetty !

Based on my understanding, the issue you are facing occurs when a matrix is poorly conditioned and used as one of the arguments for the backslash (\) or forward slash (/) operators, which are commonly used to solve systems of linear equations.

This problem arises when the matrix used in the computation is singular or very close to being singular (ill-conditioned). Attempting to solve a system of linear equations with a coefficient matrix that is singular can result in incorrect answers.

To resolve this issue, I recommend referring to the following article for more details and guidance:
