[scilab-Users] Symbolic variables in a XCOS Cblock

[Clément DAVID]

Hi,

The context is propagated at evaluation time (before compilation and
simulation) thus it's not possible to modify it on the block
implementation.

Therefore you can use interactive simulation calls (using
scicos_simulate) with a modified context. A tutorial can be found at
[1].
