Following on from #53421, Octave is overly verbose when displaying struct members that are arrays. I.e. it completely prints out the entire array.

MATLAB

>> a.b=rand(1); a
a =
  struct with fields:

    b: 0.4711
>> a.b=rand(2); a
a =
  struct with fields:

    b: [2×2 double]
>> a.b=rand(200); a
a =
  struct with fields:

    b: [200×200 double]
>> disp(a)
    b: [200×200 double]

Octave

>> a.b=rand(1); a
    a =
      scalar structure containing the fields:
        b =  0.16176
>> a.b=rand(2); a
    a =
      scalar structure containing the fields:
        b =
           0.81968   0.82219
           0.24580   0.23479
>> a.b=rand(200); a

...(pages of output)...

>> disp(a)

...(pages of output)...
