chrono::ChStateDelta Class Reference
Description
Class for incremental form of state of time-integrable objects.
Note that for many cases, this would be superfluous, because one could do y_new = y_old + dydt*td, where dydt is a ChState just like y and y_new, but there are cases where such simple "+" operations between vectors is not practical, for instance when integrating rotations in 3D space, where it is better to work with quaternions in y and y_new, but with spinors/angular velocities/etc. in dydt; so dim(y) is not dim(dydt); hence the need of this specific class for increments in states. This is a vector (one-column matrix) which extends ChVectorDynamic.
