MATLAB: How to substract one number from many numbers

minus/substract

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.

W = x - 0.6

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

W = -x + 0.6

MATLAB: “Round towards even” in sprintf

I looked through the documentation earlier today, but I could not find any evidence that sprintf() is required to conform to IEEE rounding rules. The most detailed sprintf() documentation simply indicates that the value will be rounded, without indicating that any particular rounding scheme will be used.

It is not clear at the moment that MATLAB supports round-towards-even. There is an undocumented call

   feature('setround',VALUE)

but none of the four known VALUE are for round towards even.

Historically MATLAB is known not to have used round to even; see http://www.mathworks.com/matlabcentral/newsreader/view_thread/16691
