alibPutTraceS
Replaces values in a general subset with a scalar. If the subset is a subarray then it can be more efficiently replaced with
alibPutRangeS or
alibPutSubsetS. To replace the subset values with variable values, see
alibPutTrace. The PV-WAVE API for this routine is
Array Subscripting where all subscripts are arrays of the same length.
Prototypes
void alibPutTraceSb( wvlong n, wvlong *d, wvlong b, wvlong **e, UCHAR *p, UCHAR q )
void alibPutTraceSs( wvlong n, wvlong *d, wvlong b, wvlong **e, short *p, short q )
void alibPutTraceSi( wvlong n, wvlong *d, wvlong b, wvlong **e, int *p, int q )
void alibPutTraceSl( wvlong n, wvlong *d, wvlong b, wvlong **e, wvlong *p, wvlong q )
void alibPutTraceSf( wvlong n, wvlong *d, wvlong b, wvlong **e, float *p, float q )
void alibPutTraceSd( wvlong n, wvlong *d, wvlong b, wvlong **e, double *p, double q )
void alibPutTraceSc( wvlong n, wvlong *d, wvlong b, wvlong **e, COMPLEX *p, COMPLEX q )
void alibPutTraceSz( wvlong n, wvlong *d, wvlong b, wvlong **e, DCOMPLEX *p, DCOMPLEX q )
Parameters
n — (Input) The number of dimensions in the array containing the subset to be replaced.
*d — (Input) The n-element array of dimensions for the array containing the subset to be replaced.
b — (Input) The number of elements to be replaced.
**e — (Input) The n-element array of pointers to b-element index arrays. The n b-element index arrays e define the b elements to be replaced.
*p — (Input/Output) The array containing the subset to be replaced. On output, each value in that subset has been replaced with the given scalar.
q — (Input) The scalar value which replaces each value in the subset.
