[Octave-bug-tracker] [bug #43650] reshape says "internal error: dimension mismatch across fields in struct"

[Rik]

Update of bug #43650 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #1:

This is an odd, odd thing.  The incorrect behavior is apparently confined to
instances where the reshape dimensions are the same as the original, except
for additional trailing singleton dimensions.

Examples:


octave:1> x.a = 1
x =

  scalar structure containing the fields:

    a =  1

octave:2> reshape (x, [1 1 0])
error: reshape: can't reshape 1x1 array to 1x1x0 array
octave:2> reshape (x, [1 1 1])
error: internal error: dimension mismatch across fields in struct
octave:2> reshape (x, [1 1 2])
error: reshape: can't reshape 1x1 array to 1x1x2 array
octave:2> reshape (x, [1 2 1])
error: reshape: can't reshape 1x1 array to 1x2x1 array


The same thing is seen for an array of structs.


octave:2> x(2).a = 2
x =

  1x2 struct array containing the fields:

    a

octave:3> reshape (x, [1 2 1])
error: internal error: dimension mismatch across fields in struct
octave:3> reshape (x, [2 1 1])
error: internal error: dimension mismatch across fields in struct
octave:3> reshape (x, [2 1])
ans =

  2x1 struct array containing the fields:

    a
