Finding Indices Greater Than a Specified Value in a List

BabyDoragon — Tue, 01 Jul 2025 10:14:36 GMT

As shown in the JSL below, in the case of a Matrix, 'loc' can be used to display indices greater than 5, but it cannot be applied to a List. How should I find the indices greater than a certain value in the case of a List?

show(Loc( [5, 7, 3, ., 5] >= 5 ));
show(Loc( {5, 7, 3, ., 5} >= 5 )); //Error

Convert the list into a matrix

Show(Loc(Matrix({5, 7, 3, ., 5} >= 5)));

Or you can use Where

Where({5, 7, 3, ., 5} >= 5)
