trnSet = datastore("trainingSet.csv");
trnSet.ReadSize = 'file';
trnSet.TreatAsMissing = 'na';
trnSetR = read(trnSet);
coloumn = trnSetR.Properties.VariableNames;
trnSetR = table2array(trnSetR);
for k=1:height(trnSetR)
[parmHat,parmCI] = wblfit(vec)
How do I do a Weibull analysis of a data colomun with 60000 data sets?
Above is what I have so far, but it is giving me an error at vec=zeros(1,height(trnSetR));

it says check for missing argument or incorrect argument data type in call to function 'height'.

From 2020b MATLAB supports height function for arrays as well, but it seems like you are using a previous version so its better to use another alternative to height function for array that is size function.
Using this line will help you run your script.
Refer to the following link to know more about size function

Now it says
X must be a vector containing positive values.
Error in (line 11)
[parmHat,parmCI] = wblfit(vec);
