Cronometer comparation for rally

Hi! I would like to compare the cronometer time with the time calculated, and output must be the time in seconds late or advanced. My code now is:

k=1;

v=44;

do=0.55;%Initial distance

tstart=datetime(0,0,0,0,30,0);%start time

w=datenum(tstart);%Convert double precision

d=input('Entre o valor do hodômetro:'); %Enter odometer value

a=((k*(d-do))/v); %Calculate the time

b=a*3600; %Convert to seconds

f=datenum(0,0,0,0,0,b); %Convert to double precision

T=w+f;

h=datestr(T,13)

I wouldn't use datetime here. Since your times are in units of seconds I'd probably store that data as a duration array instead.

A = rand(1000);
tic
s = svd(A);
t = toc;
timing = seconds(t)

timing = duration
   0.25529 sec

You can do some arithmetic and relational operations on duration arrays.

tenth = seconds(0.1);
tookTooLong = timing > tenth % Did the call take longer than a tenth of a second?

tookTooLong = logical
