ThresholdFactor is documented as a nonnegative scalar, but the input check used <= 0, so a value of 0 was rejected.

BEFORE:

octave:2> A = [57 59 60 100 59 58 57 58 300 61 62 60 62 58 57];
octave:3> [TF, L, U, C] = isoutlier (A, 'ThresholdFactor', 0)
error: isoutlier: threshold factor must be a nonnegative scalar.
error: called from
    isoutlier at line 298 column 13

AFTER:

octave:2> A = [57 59 60 100 59 58 57 58 300 61 62 60 62 58 57];
octave:3> [TF, L, U, C] = isoutlier (A, 'ThresholdFactor', 0)
TF =

  1  0  1  1  0  1  1  1  1  1  1  1  1  1  1

L = 59
U = 59
C = 59

MATLAB:

>> A = [57 59 60 100 59 58 57 58 300 61 62 60 62 58 57];

>> [TF, L, U, C] = isoutlier (A, 'ThresholdFactor', 0)
