measures.expand - Function

1.3.1 expand n positions to n*(n-1)/2 baselines
Description

expand calculates the differences between a series of given measure values: it calculates baseline values from position values. The returned value is a measure, but the value of the optional output variable xyz will be set to an array of values.

Arguments


Outputs
xyz	uvw (quantity array)
	allowed:	any
	Default:	record
Inputs
v	measure (baseline, position or uvw measure)
	allowed:	any
	Default:	record

Returns
anyrecord

Example

print "\t----\t expand Ex 1 \t----"
b=me.baseline(’itrf’,’10m’,’20m’,’30m’)
print me.expand(b)
#{’return’: {’m0’: {’value’: 1.1071487177940904, ’unit’: ’rad’},
#            ’m1’: {’value’: 0.93027401411547195, ’unit’: ’rad’},
#            ’m2’: {’value’: 37.416573867739416, ’unit’: ’m’},
#            ’refer’: ’J2000’,
#            ’type’: ’uvw’},
# ’xyz’: {’value’: [10.000000000000004, 20.000000000000004, 30.0], ’unit’: ’m’}}
