elementary row operations (multiplying an equation by a non-zero constant; adding a multiple of one equation to another equation; interchanging two equations) leave the zero vector of constants on the right-hand side of the equals sign unaffected. ...
If the system of equations x-k y-z=0, k x-y-z=0,x+y-z=0 has a nonzero solution, then the possible value of k are -1,2 b. 1,2 c. 0,1 d. -1,1
Since it has a unique solution, that is, the rank of [A][A] equals to both of the rank of augmented matrix and the number of unknowns, which is 3. 5. Show if the following system of equations is consistent or inconsistent. If they are consistent, determine if the solution would ...

Solve the system of equations starting at the point [0,0]. Get fun = @root2d; x0 = [0,0]; x = fsolve(fun,x0) Equation solved. fsolve completed because the vector of function values is near zero as measured by the value of the function tolerance, and the problem appears regular...
A non-homogeneous system of equations is a system in which the vector of constants on the right-hand side of the equals sign is non-zero. This lecture presents a general characterization of the solutions of a non-homogeneous system.
