2 MATLAB Interface to Generic DLLs Primitive Types All standard scalar C data types are supported by the shared library interface. These are shown in the two tables below along with their equivalent MATLAB types. MATLAB uses the type from the right column for arguments having the C type shown in the left column. The second table shows extended MATLAB types in the right column. These are instances of the MATLAB lib.pointer class rather than standard MATLAB data types. See “Creating References” on page 2-26 for information on the lib.pointer class. MATLAB Primitive Types C Type (on a 32-bit computer) Equivalent MATLAB Type char, byte int8 unsigned char, byte uint8 short int16 unsigned short uint16 int, long int32 unsigned int, unsigned long uint32 float single double double char * cstring (1xn char array) *char[] cell array of strings MATLAB Extended Types 2-16 C Type (on a 32-bit computer) Equivalent MATLAB Type integer pointer types (int *) (u)int(size)Ptr Null-terminated string passed by value cstring Null-terminated string passed by reference (from a libpointer only) stringPtr
