For three-dimensional parameters (i.e. parameters with exactly two independent axes), this function returns a c1 x c2 - matrix, c1 being the cardinality of the first independent axis and c2 being the cardinality of the second independent axis, such that each element <a,b> of the matrix is the value of the parameter at coordinates <a,b>.
inst getValueMatrix [ depIndex [ table ] ]
The index of the dependent axis to retrieve the values of. This parameter is only necessary if there is more than one dependent axis.
If specified, values are stored in this table. Otherwise, a new table is created.
If table was specified, table is returned, otherwise a new parameter table is created and returned.
