Finding the maximum in a structure array

How would I go about finding the maximum in a structure array as well as the corresponding data with that maximum value. For example, if the structure array provided data about the name, gender, and quiz grade, how would I found the maximum (highest) quiz grade and display the name and gender corresponding to that quiz grade?

If strArray is your structure array (one structure per student), and quizGrade is the value for each structure, then to get all the grades for all the students into one vector you can do

allGrades = [strArray.quizGrade];
[maxGrade, indexOfMax] = max(allGrades);
studentWithHighestGrade = strArray(indexOfMax).studentName

Thank you. Is there a way to place all the data that is less than the maximum into a new structure?

Yes

structsToExtract = allGrades <= someValue; % someValue is less than maxGrade of course, otherwise you'd select everything.
newStruct = strArray(structsToExtract);
