What is a unique solution matrix?
What is a unique solution matrix? A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero. If this determinant is zero, then the system has an infinite number of solutions. How do you find the unique solution of a matrix? If the augmented matrix does not tell us there is no solution and if there is no free variable (i.e. every column other than the right-most column is a pivot column), then the system has a unique solution. For example, if A=[100100] and b=[230], then there is a...
