oph_sequence¶

Description¶

Behaviour

Returns an array with a list of information regarding the sequences of non-zero consecutive values in input array.

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.
info: metric to be evaluated for each sequence:
- ‘length’ returns an array with sequence lengths (default);
- ‘first’ returns the index of the first element of each sequence;
- ‘last’ returns the index of the last element of each sequence.
padding: set to ‘yes’ in case output array needs to be padded with zeros. By default no padding is used.

Return type

Binary-array.

Examples

Evaluate the sizes of sequences of non-zeros values in a measure.

oph_sequence('OPH_DOUBLE','OPH_DOUBLE',measure)

Operation type

Reduce.

Argument name	Type	Mandatory	Values	Default	Min/Max-times
input measure type	“oph_type”	“yes”	“‘oph_double’\|’oph_float’\|’oph_int’\|’oph_long’\|’oph_short’\|’oph_byte’”		“1” / “1”
output measure type	“oph_type”	“yes”	“‘oph_double’\|’oph_float’\|’oph_int’\|’oph_long’\|’oph_short’\|’oph_byte’”		“1” / “1”
measure	“binary-array”	“yes”			“1” / “1”
info	“string”	“no”	“‘length’\|’first’\|’last’”	“‘length’”	“0” / “1”
padding	“string”	“no”	“‘yes’\|’no’”	“‘no’”	“0” / “1”
