printarray — Print the contents of an array
Sfmt - If given, it is passed to printf for each element of the array. Otherwise a default format is used
Slabel - If given, it is printed before the contents of the array, to easily identify the data
ktrig - The array will be printed whenever this value changes from 0 to possitive. Can be used together with metro to print at a given time interval. A value of -1 indicates to print at each k-cycle (default = 1)
