I would like to solve

W = x - 0.6 ( Where x=0.50, 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95, 1.00, 1.05, 1.10, 1.15, 1.20, 1.25, 1.30, 1.35, 1.40, 1.45, 1.50, 1.55, 1.60, 1.65, 1.70, 1.75, 1.80, 1.85, 1.90, 1.95, 2.00, 2.05, 2.10, 2.15, 2.20, 2.25, 2.30, 2.35, 2.40, 2.45, 2.50)

I would like to minus/substract each element of x from 0.6

Please suggest.....

Thanks in advance.

在 MATLAB Online 中打开

W = x - 0.6

Or, if you want to actualy subtract x from 0.6 it would be:

W = -x + 0.6
