rowCummax

rowCummax(X)

Please see rowFunctions for the parameters and calculation rules.

rowCummax calculates the cumulative maximum values in each row of X.

m=matrix([4.5 2.6 1.5, 1.5 4.8 5.9, 4.9 2.0 NULL])
rowCummax(m)
// output
col1        col2    col3
4.5         4.5     4.9
2.6         4.8     4.8
1.5         5.9     5.9


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

tp = [[1.3,2.5,2.3], [4.1,5.3,6.2]]
tp.setColumnarTuple!()
rowCummax(tp)
// output
[[1.3,2.5,2.5],[4.1,5.3,6.2]]
