Hello, I have a table, I want to index the nearest value to the zero in each row; I have some data like -0.009, 0.0025 ( I mean negative and positive).

If I want to index nearest rows to 1 I know I can use this:

[~,i] = min(1-[TEST.model1_CC, TEST.model2_CC, TEST.model3_CC],[],2);

But I have'nt Idea how to index nearest value to the zero.
