Received the following error in utilizing legacy C-code with the S-builder function.

error C2440: 'function' : cannot convert from 'real_T' to 'double *'

Is their simple solution for this conversion to the 'real_T' type?

I think the issue might be your assignment of a value to a pointer type. Could you try first dereferencing your LHS and then assign whatever real_T value to it?

The arguments of functions in s-function builder is vector. So you may need to assign the value using vector method. For example, use a[0] = x[0] to assign value of x to a double vector variable a, where x is input variable of a function in s-function builder.
