MLPutReal32Array()

int MLPutReal32Array(MLINK link, float *a, int *dims, char **heads, int d)
puts an array of single-precision floating-point numbers to the MathLink connection specified by link to form a depth d array with dimensions dims.
  • The array a must be laid out in memory like a C array declared explicitly as float a[m][n]....
  • If heads is given as NULL, the array will be assumed to have head List at every level.
  • The length of the array at level i is taken to be dims[i].
  • MLPutReal32Array() returns 0 in the event of an error and a nonzero value otherwise.
  • Use MLError() to retrieve the error code if MLPutReal32Array() fails.
  • MLPutReal32Array() is declared in the MathLink header file mathlink.h.

    dims[0] = 2;
    dims[1] = 10;
    dims[2] = 2;

    if(! MLPutReal32Array(lp, (float *)array, (int *)dims, (char **)0, 3))
