To handle missing data and outliers in a MATLAB table, use native functions like `ismissing`, `fillmissing`, `standardizeMissing`, and `rmoutliers` to safely detect, replace, or remove invalid values, avoiding brittle comparisons and ensuring accurate data cleaning.

The best way to resample and smooth time-series data in MATLAB is by converting your data to a `timetable` and using `retime` for spacing-aware resampling and `smoothdata` for trend analysis. This unlocks safe, time-based computations and synchronization.

To compute grouped statistics and summarize tabular data in MATLAB, apply the `groupsummary` and `summary` functions to your table. These functions allow you to aggregate measurements by categories, such as calculating sums or averages by region.

Yes, you can use MATLAB timetables for time-aware filtering and sorting by applying functions like `timerange` and `synchronize`. Converting tables to timetables enables spacing-aware data operations and safe date/time manipulations.

You should avoid direct comparisons when detecting missing values in MATLAB because they are error-prone and unsafe. Instead, use `ismissing` and `standardizeMissing` to correctly identify NaNs, NaTs, and other undefined entries without legacy pattern risks.
