interpolation function returns NANs

Hey everyone,

I'm using interpolation function to create the following "I":

pulse_height        = 500E-6;

pulse_len           = 1E-9;

t_rise              = 50E-12;

t_sim = 20E-9;

t_step = 10E-12;

t_pulse             = [0, t_rise, t_rise+pulse_len, 2*t_rise+pulse_len];

I_pulse             = [0, pulse_height, pulse_height, 0];

for j = 0:t_step:t_sim;

      I = interp1(t_pulse, I_pulse, j);

end

and I end up having "I" as NAN!!

You did not happen to show the values of t_step or t_sim

You would get NaN if you tried to interpolate outside the time range given in t_pulse

Great! Thanks.
