Maybe this is also related to the error I see in textscan?

test textscan
  ***** test
 str = "Km:10 = hhhBjjj miles16hour\r\n";
 str = [str "Km:15 = hhhJjjj miles241hour\r\n"];
 str = [str "Km:2 = hhhRjjj miles3hour\r\n"];
 str = [str "Km:25 = hhhZ\r\n"];
 fmt = "Km:%d = hhh%1sjjj miles%dhour";
 a = textscan (str, fmt, 'delimiter', ' ');
 assert (a{1}', int32([10 15 2 25]));
 assert (a{2}', {'B' 'J' 'R' 'Z'});
 assert (a{3}', int32([16 241 3 0]));
!!!!! test failed
some elements undefined in return list

Running Matlab, I see ...

str = 'Km:10 = hhhBjjj miles16hour\r\n';
str = [str 'Km:15 = hhhJjjj miles241hour\r\n'];
str = [str 'Km:2 = hhhRjjj miles3hour\r\n'];
str = [str 'Km:25 = hhhZ\r\n'];
fmt = 'Km:%d = hhh%1sjjj miles%dhour';
a = textscan (str, fmt, 'delimiter', ' ');
a{:}

ans = 10

ans =   'B'

ans =  16

These test worked until:

PASSES 17 out of 17 tests

PASSES 13 out of 13 tests
