I'm decoding some data which randomly can have sign, all I know is that there is a character before the point character and there are two characters after the point. I have noticed that the first iteration in the for loop is slower than the next iterations. I'm wondering whether you have any idea about it. Is that because a kind of initialization?
Here you go a part of my code:
close all; clear all; clc;
data='-0.01-0.020.03';
inc = [0 0 0];
inc_t = 0;
xyz_accel = [0 0 0];
for j=1:3
tic
if data(1+inc_t)=='-'
xyz_accel(1,j) = str2double( data(inc_t+1:inc_t+5) );
inc(1,j) = 5;
else
xyz_accel(1,j) = str2double( data(inc_t+1:inc_t+4) );
inc(1,j) = 4;
end
inc_t = sum(inc);
toc
end
xyz_accel
Elapsed time is 0.017351 seconds.
Elapsed time is 0.000255 seconds.

xyz_accel =
Thanks in advanced.
