The question is not clear at all. How can a 4 x 5 matrix equal a 5 x 1 vector?
Do you mean the matrix representation of system of equations:
You wanted to solve Ax = 0,
First of all do you realise that the solution space is actually the nullspace of matrix A.What I've done so far:
I've used Gauss-Jordan Complete Elimination to reduce the augmented matrix...(can't go past that)
Can you write the Gauss-Jordan reduced Matrix here?
Well the solution space is a finite dimensional vector space and thus it has a dimension. Its actually the nullity of A....What I don't understand:
I know that I should use the reduced matrix to find the basis of the linear system...But I don't know how to do this...
Also, what does it mean "subspace's dimension"?
Thank you to all providing assistance
