Re: [OctDev] minmax

Yes, it seems they have a bug in their own code or that the example is just 
wrong:

>> P = {[0 1; -1 -2] [2 3 -2; 8 0 2]; [1 -2] [9 7 3]};
>> pr = minmax(P)
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] [12 5; 13 11]})

ans = 

    [2x2 double]
    [2x2 double]

>> minmax ({[0 1; -1 -2] [2 3; 8 0; 85 75]; [1 -2; 9 7] [12 5; 13 11]})
Error using minmax (line 27)
Data{1,2} and Data{1,1} have different numbers of rows.
 
>> minmax ({[0 1; -1 -2; 34 56] [2 3; 8 0]; [1 -2; 9 7; 21 23] [12 5; 13 11]})
Error using minmax (line 27)
Data{1,2} and Data{1,1} have different numbers of rows.
 
>> minmax ({[0 1; -1 -2; 34 56] [2 3; 8 0; 21 23]; [1 -2; 9 7] [12 5; 13 11]})

ans = 

    [3x2 double]
    [2x2 double]
