minLambda

lowest value of lambda different from zero for double precision

Returns

• minLambda a scalar

Discussion

Estimate the minimum value of lambda that should be considered, given the balance between the position-errors and the velocity model. lambda can always be safely set to zero, but the minimum value is still useful for a logarithmic search algorithm. If the rank of (VV) is less than N, then the solution may not be invertible if lambda is too large. The maxLambda value should prevent this.
