At the top of the documentation page for xlsread there is warning that xlsread is not recommended and it suggests alternative functions (readtable, readmatrix).
If you're checking that a particular header (variable name) exists, you can use those function to read in just the header row(s).
If you're checking if a paricular name and ID exists you'll need to read in the entire table and the search the name and ID columns (hint: isequal, strcmpi, ismember).
If you get stuck and have any problems, show us where you're at and describe the issue.

Can I use somthing like
a = input('Enter name: ');
if a == readtable('StudentIDverify.xlsx')
does this work?

Not quite.
Try reading in the table using readtable and look at what it produces.
'a' will presumably be a character vector but the readtable function will read in an entire table.
