Fixing the ‘error Singular Matrix’ error? (Ti 89)?
so I needed to resolve:
A=[2 1 1]
[1 2 2]
[2 1 1]
and
B=[2]
[3]
[0]
so I multiplied A^1B (inverse)
and I received error singular matrix error.
How you can I modify the equation in order that I can punch it into my calculator?
Calculator is a Ti84 Silver Version btw

So wait, do you will have a TI89 or a TI84 Plus SE?
Both manner, you possibly can’t “change the equation” to make it work as a result of matrix A has a determinant of zero, that means it isn’t invertible (which is why you are getting Err:Singular Matrix).
I assume you wish to remedy a linear system like Ax = B, the place A, x, and B are all matrices. Usually what you might do is increase matrix B on to matrix A after which cut back this to lowered rowechelon kind, however upon doing, you will see that the final row of your matrix will probably be [0 0 0 1]. This suggests that 0 = 1, which isn’t true, and due to this fact, the system is inconsistent and an answer to this method doesn’t exist.

If you’re looking for a regression for plotted factors, then I am fairly certain the singular matrix error simply signifies that the calculator can not discover a perform to match the plot. Apart from that, I don’t know.
