使用正则表达式库从字符串中提取数字

Question

So I already know that to get substrings of a string I might use the regex library but the examples I see allows me to get simple substrings.

I have this string:

string sensorsData = "M -14.520000 -21.180000 -46.139999 A 1.745373 8.829816 4.515464 G -0.244478 0.210922 -0.100135 "
         "R 0.509321 0.019607 0.211065 0.834062 g 1.787680 8.412998 4.711269 L - 0.037518 0.426394 - 0.152709 P 5.000000"
         "D - 5.496490 - 61.296814 - 21.143848";

What would be the best approach to get every single number from the string? I am using the letters so that I can know what means values. Thanks.
