(Lecture 29) andboth employ the same formulas for computing the entries of the solutions.Recall: An m n matrix A has an orthonormal set of columns if and only if A*A=eye(n).If a matrix A does not have orthonormal columns, we can, first, generate an orthonormal basisU for Col A, ...

More equations than variables is only supported for polynomial systems." And when i try to use "solve" , then i get the message: "Warning: Unable to find explicit solution" and empty sym. Can you help me to solve this? this is the code i have when i tried fsolve...
The suggestions in this section should help diagnose and solve issues with numerical instability, in particular UNKNOWN solution status or solutions with large violations. Since numerically stable models tend to solve faster, following these hints can also dramatically shorten solution times....
