Table Functions
These functions work with general multi-dimensional tables that contain sub-tables within the primary table. They also support tables with or without keys and with any type of values. Their names have an extra "n" appended to signify that they support table with higher dimensions. Most are generalizations of the Array Functions that support only 1-dimensional arrays. However, none of these functions support class objects or lists of numbers. Most functions perform some type of mathematical processing by selecting only the numeric values in the table.
Several of the table functions return the processed table which can become the input of another function. For example, the following table equation is possible: x = meann( muln( addn( tbl, 20.5), 0.42 ) )). This adds 20.5 to all numeric value in table tbl, then multiples that by 0.42, then calculates the mean value x.
