TYP::IsSkewPart --
tests whether the argument is a skew partition
Call(s)
TYP::IsSkewPart(expr)
Parametersexpr | - | any expression |
Introduction
The TYP::IsSkewPart function tests whether expr is a skew partition that is a
a list with two components l1 and l2, l1 being the exterior
shape, l2 the interior shape.
The diagram of bixes needs not to be connected, the condition being that the
diagram of l2 must be included into the one of l1.
Example 1>> muEC::TYP::IsSkewPart( [[3,1,1], [2,1]] );
TRUE
>> muEC::TYP::IsSkewPart( [[4,2], [3,3]] );
FALSE
