Seems we have mxIsStruct, mxGetNumbertOfFields and mxGetFieldNameByNumber to use but why (asks the lazy one) no mxIsField?

Equivalent to mxIsField:
mxGetFieldNumber(Struct, Name) != - 1
Usually the user does not just want to check the existence, but access the data in addition. Therefore mxGetFieldNumber is more efficient in the most cases.
