Storing indices from a matrix

16 次查看(过去 30 天)
Hye all. I am relatively new with Matlab. I am modelling a vehicle suspension system right now.
Assume I have a column matrix that has 6 elements. A= [ 1 2 3 -4 6 -2]'
I want to extract the index of the values that are negative, and store all of them as a column matrix or an array 'B'.
Expected result : B= [4 6]
Kindly help.
