oph_sub_array

Description

Behaviour

It subtracts each value of measure array b from the value in the same position in measure array a.

Parameters

  • input measure type: Ophidia typing. Supported types are pairs of: ‘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 a: first input measure.
  • measure b: second input measure.
  • missingvalue : value to be considered as missing value; by default it is NAN (for “oph_double” and “oph_float”).

Return type

Binary-array.

Examples

Subtract each value of measure array b from the value in the same position in measure array a.

oph_sub_array('OPH_DOUBLE|OPH_DOUBLE','OPH_DOUBLE',measure_a,measure_b)

Operation type

Simple.
