MATLAB: Hi, there is a (1×6) vector that i want to extract values from. I used strings to pick-up the subtitle and now the problem is that i have to extract every value under the subtitle (e.g Oxygen). How to i extract those values without hardcoding

extract valuesMATLAB

InputData;
strmeasurements = Measurements;
'Oxygen';
strcmp(strmeasurements,'Oxygen')
for = 1:1:length(strmeasurements)
if strcmp(strmeasurements,'Oxygen') > 0

It would probably make a more sense to use the table data type instead of a string array that is parsed to separate variables.
