Data contains 2 columns (plan and T). However, plan contains some NaN. I would like to delete the NaN from plan and also its corresponding values in T so that the good data from columns plan and T will be of the same dimension

Assuming data is an m x 2 matrix, it's simply:
Data(isnan(Data(:, 1)), :) = []
That is, find the nan in the first column of Data ( isnan(Data(:, 1))), and removes all the rows for which isnan is true ( Data(trueorfalse, :) = [])

Please, after deleting I would want to give them different names. How do I store them separately after deleting?

Then you don't delete, you only copy the data you want to keep (everything that is not nan)
tokeep = ~isnan(plan); %use ~ for logical not
newplan = plan(tokeep);
newT = T(tokeep);
See the help on finding values that meet a condition in the documentation
