text: Furthermore, the matrix may be singular for dependent equations, the inversion can be unstable in the presence of noise and the system may be under-constrained if parameters other than the primary variables inverted for, are desired.
text: But it rapidly turned out that the inversion is an unstable process : noise and errors can be tremendously amplified making a direct solution hardly practicable.
