Sum of all rows into a list

Question

I'm trying to take the sum of all of my rows and add it to a list.  So, the sum of row 1 will be item 1, sum of row 2 will be item 2, etc.  Is there an easy way to do this using jsl?

Here is one way to do it.  Others may have better methods

Names Default To Here( 1 );
dt = Current Data Table();
sumMatrix = [];
For Each( {col}, dt << get column names( string, numeric ),
	sumMatrix = sumMatrix || Col Sum( Column( dt, col ) )
);

You can also use matrix calculations, below is one option

Names Default To Here(1);

dt = open("$SAMPLE_DATA/Big Class.jmp");

m = dt << get as matrix;

sums = V Sum(m`);

tolist = As List(sums)[1];
