How to change the sign of a whole vector?

Hi, I want to plot the displacements from a compressive test, but my data is in negative sign. I have a vector like this but much longer of 588 columns in one row: A[ -0.1039 -0.1085 -0.1084 -0.1108 -0.1126 -0.1107] How can I change the sign of all the values to plot a positive graph? Thank you! Martha
