alibPutSubsetS
Replaces values in a general subarray with a scalar. If the subarray is contiguous then it can be more efficiently replaced with
alibPutRangeS. To replace the subarray values with variable values, see
alibPutSubset. The PV-WAVE API for this routine is
array indexing with at least one index array and at least one scalar or range operator.
Prototypes
void alibPutSubsetSb( wvlong n, wvlong *d, wvlong *b, wvlong **e, UCHAR *p, UCHAR q )
void alibPutSubsetSs( wvlong n, wvlong *d, wvlong *b, wvlong **e, short *p, short q )
void alibPutSubsetSi( wvlong n, wvlong *d, wvlong *b, wvlong **e, int *p, int q )
void alibPutSubsetSl( wvlong n, wvlong *d, wvlong *b, wvlong **e, wvlong *p, wvlong q )
void alibPutSubsetSf( wvlong n, wvlong *d, wvlong *b, wvlong **e, float *p, float q )
void alibPutSubsetSd( wvlong n, wvlong *d, wvlong *b, wvlong **e, double *p, double q )
void alibPutSubsetSc( wvlong n, wvlong *d, wvlong *b, wvlong **e, COMPLEX *p, COMPLEX q )
void alibPutSubsetSz( wvlong n, wvlong *d, wvlong *b, wvlong **e, DCOMPLEX *p, DCOMPLEX q )
Parameters
n — (Input) The number of dimensions in the array containing the subarray to be replaced.
*d — (Input) The n-element array of dimensions for the array containing the subarray to be replaced.
*b — (Input) The n-element array of dimensions for the subarray. Some can be equal to 1, i.e., the subarray can have less than n dimensions.
**e — (Input) The n-element array of pointers to the index arrays defining the subarray to be replaced. Some can be 1-element arrays, i.e., the subarray can have less than n dimensions. Number of elements in array e[i] is b[i].
*p — (Input/Output) The array containing the subarray to be replaced. On output, the subarray has been replaced.
q — (Input) The scalar value which replaces each value in the subarray.
