CubeItemTyperepresents a cube of values like a spatial particle distribution, where the particle position is given by X which is the column, Y the row and Z the depth. In the example of a spatial partical distribution, the value is the particle size. CubeItemTypeis formally defined in Table 12.

Engineering units and range for the Valueare defined by corresponding Propertiesinherited from the ArrayItemType.

The DataTypeof this VariableTypeis restricted to SByte, Int16, Int32, Int64, Float, Double, ComplexNumberTypeand DoubleComplexNumberType.

The ArrayDimensions Attributefor Variablesof this type or subtypes should use the first entry in the array ([0]) to define the number of columns, the second entry ([1]) to define the number of rows, and the third entry ([2]) define the number of steps in the Z axis, assuming the size of the matrix is not dynamic.
