You have a couple options. If you just want to find the row for Mary, you can use option 1. If you specifically want an if/else statement, you can loop through each row and output the info using option 2.
% read in the data
[~, exceldata] = xlsread('excel-file.xlsx');
% Option 1: find the relevant index for Mary
idx= find(strcmp(exceldata(:,1), 'Mary'));
fprintf('%s, Major: %s, Course: %s\n', exceldata{idx, 1:3});
% Option 2: using a loop
for i=1:size(exceldata,1),
if strcmp(exceldata{i,1}, 'Mary'),
fprintf('%s, Major: %s, Course: %s\n', exceldata{i, 1:3});
fprintf('no data\n');

Thank you that helped a lot! I needed something like option 2. Is there a way so that only one result is displayed instead of an output for each row? For example, if the conditions are met, only Mary's name and major is displayed and if they are not, "No Data" is displayed only once.
Thank you again!
