MATLAB: Filling out an empty column in an existing table based on conditions matching other columns

table columns

I have a table. If column 3 is "fast" AND column 4 contains any of these characters: boat, car, or airplane. then column 5 become those strings on column 4. If it meets just the "fast" in column 3, then column 5 becomes "fast". Otherwise it's none. Do I need an if else statement? Or how would I do this? 
column 3
fast
fast
slow
medium
fast
column 4
mike boat day
pax airplane oscar
ship
car
train
column 5
boat
airplane
none
none
fast

Best Answer

% t1 = yourtable
logic1 = startsWith(t1.column3varname,'fast') & startsWith(t1.column4varname,{'boat' 'car' 'airplane'});
logic2 = startsWith(t1.column3varname,'fast') & ~startsWith(t1.column4varname,{'boat' 'car' 'airplane'});
t1.column5varname(logic1) = t1.column4varname(logic1);
t1.column5varname(logic2) = t1.column3varname(logic2);
t1.column5varname(~logic1 & ~logic2) = {'none'};
