Re: script failure with 2.1.50

[Henry F. Mollet]

I've tried the commands in your script at the octave prompt and I got a
plot.

octave:6> plot(Tr, f); % worked and produced a curve  f=0 from Tr = 0 to 1,
then a step to 0.5, then a slanted step, then smoothing out and increasing.
"Default" x-axis from 0-10, "default" y-axis from -0.1 to 0.9.
