ssGetRWorkValue (Writing S-Functions)

Get an element of a block's floating-point work vector

Syntax

real_T ssGetRWorkValue(SimStruct *S, int_T idx)

Arguments

S
SimStruct representing an S-Function block.

idx
Index of the element returned by this function.

Description

Returns the idx element of the the floating-point work vector used by the block represented by S. The vector consists of elements of type real_T and is of length ssGetNumRWork(S). Typically, this vector is initialized in mdlStart or mdlInitializeConditions, updated in mdlUpdate, and used in mdlOutputs. You can use this macro or ssGetRWork to get the current values of the work vector in the simulation loop, mdlInitializeConditions, or mdlStart routines.

Example

The following statement

```
real_T v = ssGetRWorkValue(s, 0);
```

is equivalent to

real_T* wv = ssGetRWork(s);
real_T v = wv[0];
