oph_gsl_quantile¶

Description¶

Behaviour

It computes the quantile(s) specified as q1,q2,... on the elements of the measure array ordered in an ascending way.

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.
q1: order of one mandatory quantile.
q: one or more orders of one or more quantiles.
order safe flag:
- with ORDER_SAFE_FLAG_SET (default), the input will be ordered;
- with ORDER_SAFE_FLAG_UNSET, the input is considered already ordered in ascending way,
- with INDEX the indexes of the nearest values to quantiles are returned.

Return type

Binary-array.

Examples

Compute quantiles of order 0.10, 0.60 and 0.80.

oph_gsl_quantile('OPH_DOUBLE','OPH_DOUBLE',measure,0.10,0.60,0.80)

Operation type
