Type miss-match in calling mex function (Uint16_T)

Hi,

I am running Matlab 7.7.0 (R2008b) on a windows machine. I am running the Statistical Pattern Recognition Toolbox for Matlab. http://cmp.felk.cvut.cz/cmp/software/stprtool/. The matlab m file calls a mex function. The type in signature in c file is uint16_T *. I am passing a double array which is being casted as uint16(I). When I run the code it is giving the following error:

Undefined function or method 'qpssvm_mex' for input arguments of type 'uint16'.

Calling code:

[x,exitflag,t,access,History] = qpssvm_mex(H,f,b,uint16(I),x0,...
        options.tmax,options.tolabs,options.tolrel,options.verb);

MEX function signature:

void mexFunction( int nlhs, mxArray *plhs[],
                  int nrhs, const mxArray *prhs[] )
{
  int exitflag;      /* status of the solution (output arg) */
  long t;            /* number of iterations (output arg) */
  double *x;         /* solution vector (output arg)*/
  double *History;   /* UB and LB history (output arg) */
  int verb;          /* verbosity (input arg)*/
  long tmax;         /* max number of iteration (input arg)*/
  double tolrel;     /* stopping condition (input arg) */
  double tolabs;     /* stopping condition (input arg) */
  double *x0;        /* initial solution (input arg)*/
  double *f;         /* vector f (input arg) */
  double b;          /* scalar b (input arg) */
  uint16_T *I;       /* vector of uint16_T (input arg) */
  double *diag_H;    /* diagonal of matrix H */
  long i ;           /* loop variable */
  double *tmp_ptr;

Any help will be greatly appreciated.

What is the result of "which qpssvm_mex"
