When CSV logs or simulation outputs exceed RAM, MATLAB tall arrays let you write normal-looking code that executes lazily in chunks. Here is the mechanism, a worked mean-over-many-files example, and the mistakes to avoid.
MATLAB tall arrays defer execution until gather(), letting you run familiar table operations on data larger than RAM. See a grouped-statistics example on 50 GB of sensor logs, plus the memory, debugging, and performance trade-offs before adopting.
Learn how MATLAB tall arrays let you run familiar table syntax on data that doesn’t fit in memory, and understand when they are the right engineering choice.
