ssGetdX - Get the derivatives of a block's continuous states
Syntax
real_T *ssGetdX(SimStruct *S)
Arguments
- S
SimStruct representing an S-Function block or Simulink model.
Returns
A pointer (real_T *) to an array containing
the derivatives of the continuous states of S,
which can be a block or the model. Returns NULL if
there are no continuous states.
Description
Use this macro in mdlDerivatives to
get the derivatives of a model or block's continuous states. Use ssGetNumContStates(S) to
get the length of the array.
Note
The pointer returned by this macro changes as the solver evaluates
different integration stages to compute the integral. |
Languages
C, C++
Example
See the S-function matlabroot/toolbox/simulink/simdemos/simfeatures/src/csfunc.c used
in sfcndemo_csfunc.mdl and
the S-function matlabroot/toolbox/simulink/simdemos/simfeatures/src/sfun_atol.c used
in sfcndemo_sfun_atol.mdl for
examples using this function.
