dimension of the matrix n = len(a) # Check if the matrix is square if n != len(a[0]): raise ValueError("Matrix must be square.") # Base case: for a 1x1 matrix, return the single element as the determinant if n == 1: return a[0][0] # Recursive case: calculate the determinant using cofactor expansion
