oph_extract

Description

Behaviour

It returns a subset of a measure obtained using the (long long) indexes passed as ‘index list’.

Parameters

  • input measure type: Ophidia typing. Supported types are: ‘oph_double’; ‘oph_float’; ‘oph_long’; ‘oph_int’; ‘oph_short’; ‘oph_byte’.
  • output measure type: Ophidia typing. Supported types are: ‘oph_double’; ‘oph_float’; ‘oph_long’; ‘oph_int’; ‘oph_short’; ‘oph_byte’.
  • measure: input measure.
  • index list: binary array with (long long) indexes.

Return type

Binary-array.

Examples

Extract the specified subset of measure.

oph_extract('OPH_DOUBLE','OPH_DOUBLE',measure,index_list)

Operation type

Simple.
