## Syntax

`*SolverDiffEquation(varname, "label")`

## Arguments

- varname
- The variable name for the solver array differential equation.
- "label"
- The descriptive label for the solver differential equation.

## Example

```
*SolverDiffEquation( sde_equation1, "Example Diff Eq" )
*SetSolverDiffEquation(sde_equation1, , EXPLICIT,
`DIF1(sde_equation.id) + 8.0 + COS(TIME)` )
```
