I have a 56x4 table in which first column collects strings, while the other columns have non-null number.
edgetable=table(edgetype,edgeindex,firstnode,secondnode);
I would like to extract edgeindexes such that edgetype is equal, e.g., to "CSE".

Let's make a sample table.
rng default
listOfTypes = ["apple"; "banana"; "cherry"];
T = listOfTypes(randi(numel(listOfTypes), 5, 1));
x = randi(10, 5, 1);
tt = table(T, x)
tt = 5×2 table
T x ________ __ "cherry" 1 "cherry" 3 "apple" 6 "cherry" 10 "banana" 10
theCherries = tt(tt.T == "cherry", :)
theCherries = 3×2 table
T x ________ __ "cherry" 1 "cherry" 3 "cherry" 10
