MATLAB: Question on how to code something

vector

Hi all,
My program produces two vectors which indicate current over time:
t_vec = [25 33 58 100]
I_vec = [50 0 -50 0]
which means that the current is 50 on the time interval [0,25], current 0 on [25,33] etc.
Now I want to extend both vectors so they give the current at every multiple of 10 sec as well:
T_vec = [0 10 20 25 30 33 40 50 58 60 70 80 90 100]
This T_vec I managed to make with "sort(0:10:100,T_vec)" , but the corresponding current vector
I_vec = [50 50 50 50 0 0 -50 -50 -50 0 0 0 0 0]
is more difficult to produce. Any suggestions? Thanks in advance!

  • [counts, bins] = histc( T_vec, t_vec );
    expanded_I_vec = I_vec(bins);
