matlab - how to use mxNumericArray -

my goal homecoming uint32 number:

i have been using mexcreatedoublescalar , alter mxcreatenumericarray

the old code is

const int all_good 0; plhs[0]=mexcreatedoublescalar(all_good);

the new code want

const int all_good 0; int dim[2]; dim[0]=dim[1]=1; plhs[0]=mxcreatenumericarray(2,dims,mxuint32_class,mxreal);

how can set value all_good in plhs[0], or batter way homecoming uint32 mex?

you can utilize mxcreatenumericmatrix more simple general mxcreatenumericarray create container mxarray, utilize mxgetdata pointer actual memory of allocated scalar , assign value it.

const int all_good = 0; // need assignment here... plhs[0] = mxcreatenumericmatrix( 1, 1, mxuint32_class,mxreal); // create scalar unsigned int* ptr = (unsigned int*)mxgetdata( plhs[0] ); ptr[0] = all_good; // assign value plhs[0]
