  • SymbolicC expressions are inert; they evaluate to themselves, staying in an unevaluated form.
  • SymbolicC expressions can be converted into a C string with ToCCodeString.

Examples

Basic Examples  (1)

To use SymbolicC you first need to load the package:

In[1]:=
Click for copyable input

This creates a preprocessor if conditional directive:

In[2]:=
Click for copyable input
Out[2]=

This creates an entire if/else/endif set of statements:

In[3]:=
Click for copyable input
Out[3]=

This adds a comment to the if directive:

In[4]:=
