I use tabulate command like this:
a = array(352360x1)
b = tabulate(a)
b = array *(19231x3)*
Why is B array shorter than A ? Thanks

The number of rows in the output of 'tabulate' is the number of unique values in the input, so there must have been 19231 unique values among the 352360 elements of your 'a' array. Read the description of 'tabulate' at:
