The unit_MATLAB can pass a C::E sparse matrix to Matlab.
Also, there was a bug in previous version: dense matrices were passed as transposed. Fixed.
The ChLcpMatlabSolver is a solver that can be plugged into the ChSystem, so that the Matlab solver will be used to solve the linear system (for the moment this is limited to linear systems, not to LCP or CCP, but it could be adapted in future).
The Matlab "A\b " style linear solver is used.
This can be used to test finite elements problems that require very high precision (the default iterative solvers would need preconditioning, that is not yet available in C::E, natively)
New feature in the Irrlicht interface:
  press F11 and do linear statics,
  press F10 and compute non-linear statics.
Major refactoring in ChSystem!
Lot of old code has been removed, to avoid confusion. Deprecated/outdated functions have been removed. The code looks clean, yet the backward compatibility shouldn't be broken.
Functions to set zero speed to FEM nodes (used, for example, after a static analysis has been performed)
The Euler-Bernoulli beam class is complete.
Now it also includes the projectors for the Haugen-Felippa-Rankin-Omid corotational approach, for precise tangent stiffness.
Various fixes and changes.
Updated test code for FEM (but not final! here the Matlab unit is used to solve FEM for precise benchmarks)
