I'm attempting the same: Passing a matlab structure to C, and unwrapping it using all of the built in mxarray functions. I thought the following example on the Mathworks documentation site would be helpful (http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/f42645.html), but typing it verbatim, I get errors. I'm using R2008a. Does anyone have experience with the libstruct function?

>> sm.p1 = 476; sm.p2 = -299; sm.p3 = 1000
sm =
p1: 476
p2: -299
p3: 1000
>> sc = libstruct('c_struct', sm)
??? Error using ==> feval
Undefined function or method 'lib.c_struct' for input arguments of type 'struct'.

Error in ==> libstruct at 17
ptr=feval(['lib.' structtype],initialvalue);
