MATLAB: Char to Double convertion

Question

I want to plot data given from a device that outputs the values as "Char", (see below).

I would like that the values appear as the ones shown in "figure 2".

Is it possible?

Answer 1

>> str = 'LVLG -287.41E-03 -28.401E-03 -2.4001E-03';
>> tmp = regexp(str,'\S+','match');
>> vec = str2double(tmp(2:end))
vec =
  -0.2874100  -0.0284010  -0.0024001
