Fri 27 May 2022 03:21:56 PM UTC, comment #2: Verified that the code no longer produces an error and that the output appears equivalent to Matlab. Marking as Fixed and closing report.	Rik <rik5>
Thu 26 May 2022 05:49:41 PM UTC, comment #1: Thank you for your report. I pushed a change to the stable branch that should fix this issue: https://hg.savannah.gnu.org/hgweb/octave/rev/0938366560cf It should be part of Octave 7.2.0. Marking as ready for test.	Markus Mützel <mmuetzel>
Thu 26 May 2022 01:43:10 PM UTC, original submission: subplot() has two usages, either you give a numbr of rows and columns and select the axis with an index, or you can request the axis by setting the 'position' of the subplot. When mixing these two, you get an error. For example, subplot(2, 2, 1) subplot('position', [0.5, 0.5, 0.3, 0.3]) returns an error in the second line in subplot.m, line 296. The error comes from the fact that a variable "rows" is requested that has not been submitted in the function call. The problem seems to have been introduced when fixing bug #59076, it is not present in Octave 5.2. I am aware that mixing these two forms is a bit special, so the error may well be intentional. On the other hand, it is a regression and that Matlab eats this setup just fine.	Anonymous
