Hi, there is a (1x6) 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 ?

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.
a=["Oxygen" "CarbonDioxide" "Temperature" "Pressure" "SolarRadiation"
"19.126323" "2316.074" "20.22159" "100.55903" "5.5317028e-05"
"21.649558" "1675.8466" "19.700265" "97.258761" "4.7879645e-05"
"21.365389" "5137.8534" "17.95304" "100.52854" "2.3418843e-05"
"20.849494" "4038.5941" "20.266467" "67.042816" "6.0612875e-05"
"20.435402" "1735.1865" "22.257325" "74.053206" "4.8704271e-05"

"21.355073" "2823.8126" "18.492655" "72.283582" "6.6637808e-05"];
for col=1:size(a,2)
L=ismember(a(1,:),a(1,col));
data=str2double(a(2:end,L));
switch a(1,col)
case "Oxygen"
Oxygen=data;
case "CarbonDioxide"
CarbonDioxide=data;
case "Temperature"
Temperature=data;
case "Pressure"
Pressure=data;
case "SolarRadiation"
SolarRadiation=data;
otherwise
%deal with unexpected input here
error('data type not recognized')
end
end
