Hi Giorgio
could you please tell me what matlab's minmax returns in the following cases?
minmax (1)
minmax ([i 2; 3 4])
minmax (rand (2,2,2))
minmax ({[0 1; -1 -2] [2 3 -2; 8 0 2]; [1 -2] [9 7 3]})
minmax ({[0 1; -1 -2] [2 3; 8 0]; [1 -2] [9 7 3]})
minmax ({[0 1; -1 -2] [2 3 -2; 8 0 2]; [1 -2] [9 7 3; 8 0 2]})
I would expect that some, maybe all, will fail but would like to be
sure to fix this.

Re: [OctDev] minmax
Hi,
I recently ran into these troubles too.
It's nice if this can get fixed. And unless some particular reason I may not
know, I would suggest to use the same name as in matlab (minmax instead of, or
in addition to min_max) so code is consistent.
I also checked what you asked in matlab r2012b:
minmax (1)
ans =
1 1
minmax ([i 2; 3 4])
Error using minmax (line 27)
Data is complex.
minmax (rand (2,2,2))
Error using minmax (line 27)
Data is not two-dimensional.
minmax ({[0 1; -1 -2] [2 3 -2; 8 0 2]; [1 -2] [9 7 3]})
Error using minmax (line 27)
Data{1,2} and Data{1,1} have different numbers of columns.
minmax ({[0 1; -1 -2] [2 3; 8 0]; [1 -2] [9 7 3]})
Error using minmax (line 27)
Data{2,2} and Data{1,1} have different numbers of columns.
