Hello, I want to transmit 1x12 binary data to mex file for data transmission
b=70.19
Y = round(b,1);
dec= Y*10;
integers=dec;
temp = integers;
a=decimalToBinaryVector(temp, 12);
The output binary values (a) is : 0 0 1 0 1 0 1 1 1 1 1 0
When I pass these values to mex file,
b= mex(a);
I get a different binary value. The output of a is:
1.18870000000000e-320 1.18870000000000e-320 1.00000000000053 1.18870000000000e-320 1.00000000000053 1.18870000000000e-320 1.00000000000053 1.00000000000053 1.00000000000053 1.00000000000053 1.00000000000053 1.18870000000000e-320
mex.c
void mexFunction( int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[] )
{
double *a;
int M,N;
double* bb; /* 1xN output matrix */
const mwSize *dims;
a=mxGetData(prhs[0]);
plhs[0] = mxCreateDoubleMatrix(M, N, mxREAL);
bb = mxGetPr(plhs[0]);
analogoutputMatlab(a,bb,N);
}
Why do I get change in binary values? How to pass binary values to mex?

Walter, yes I will try the example with session based interface.
