rowMove

rowMove(X, steps)

Please see rowFunctions for the parameters and calculation rules.

steps is an integer indicating the length to shift the row elements of X.

• if steps is positive, the elements in each row are shifted to the right by steps position(s).

• if steps is negative, the elements in each row are shifted to the left by steps position(s).

• if steps is 0, X is not shifted.

The rowMove function shifts the elements in each row of X left or right by a specified number of steps.

m=matrix([4.5 2.6 1.5, 1.5 4.8 5.9, 4.9 2.0 NULL])
rowMove(m, 2)          

rowMove(m, -2)

a=array(INT[], 0, 10).append!([1 2 3, 4 5, 6 7 8]);
rowMove(a, 2)
// output
[[00i,00i,1],[00i,00i],[00i,00i,6]]

tp = [[1.3,2.5,2.3], [4.1,5.3,6.2]]
tp.setColumnarTuple!()
rowMove(tp, -2)
// output
[[2.3,00F,00F],[6.200000000000001,00F,00F]]
