[Octave-bug-tracker] [bug #53881] [octave forge] (control) impulse response differs greatly on i386 vs x86_64

[Mike Miller]

Follow-up Comment #1, bug #53881 (project octave):

Sorry, I was playing with different time steps. The scripts that I pasted
should be


pkg load control
sys = tf ([1, 1], [1, 2, 1]);
y = impulse (sys, [0:999] ./ 1000).';
save results32.txt


and


pkg load control
sys = tf ([1, 1], [1, 2, 1]);
y = impulse (sys, [0:999] ./ 1000).';
results32 = load ('results32.txt');
fprintf (stdout, '%4u  %-17.15g  %-17.15g\n', [0:999; results32.y; y]);


to get the data arrays and divergence that I showed in the original post.
