In the first test suite, Robinson and Reed both have the same age, so I think either the test suite should be improved or Reed's age in the .mat file should be changed.

rh x = I don't think you need the [] in your max matrix.

where I can get the standard answer?

Easy staff. Don't think too much. First find the maximum age, then use the index of the maximum age and by using that you'll find the corresponding name.

not bad

I solved the problem in MATLAB but on here it did not work. I found the index of the maximum number in the variable age, and then used that to output a name with the same index in the name variable.

I am puzzled as to why this solution is flagged.

So what this does is it finds the number where age is equal to the max age, and then that corresponding number gives the position of names that has the max name.
