Question on how to code something

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!

? You cannot use two numeric vectors as input to sort() ?

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

Thank you, the histc command was what I was looking for.
