Suppose I have the following list: list = {{-1, 4, -5, 6}, {-5, - 4, 3, 1}} Now I want to select only the negative elements of each sublist of this list. So I would like to get the following result: {{-1,-5},{-5,-4}}. I have tried GreaterThan[0] /@ list, but that does not work, although Max /@ list does work if one wants the maximum value of each sublist, and also Total /@ list if one needs the total of each sublist. How do I solve this problem? Thanks in advance for your help. .
