Sentence examples for difficult to compute in from inspiring English sources

The low-rank solutions of continuous and discrete Lyapunov equations are of great importance but generally difficult to compute in control system analysis and design.

This integration is difficult to compute in practice; so, Laplace approximation is used to approximate the posterior by a Gaussian distribution and thereby simplify this integration.

Unfortunately, the interaction effect was difficult to compute in STATA package due to the extremely large sample size in this study.

The utility function based on the entropy is difficult to compute in practice since we need to have the measurement before deciding how useful it is.

P-invariants of a biological reaction model are not so difficult to compute in most cases.

We do not use Bayes factors here because they can be difficult to compute in practice, and are numerically unstable when proper, but diffuse priors are used [ 35].

However they are difficult to compute either in the gas phase or in periodic solid structures experimentally, thus their existence in perylene molecular crystal is easier to be carried out through theoretical work.

Although the substitution model derivatives can be computed analytically in the homogeneous case as well as in Galtier and Gouy's model, they are difficult to compute analytically in the more general case, and are consequently computed numerically in Bio++.

Confidence limits for forecasts more than one period ahead will generally widen as the forecast horizon increases, due to uncertainty about the level and trend as well as the seasonal factors, but it is difficult to compute them in general by analytic methods.
