Can you explain what you mean? I am trying to convert a program to tall arrays because my data set is to large. So the first step i took was simply to convert my data to tall arrays

However, i have a loop that does work on the tall array after its formed. Some of the work are simply things like strcat(array{1,2},array{1,3})

However i cant do that because it says indexing with brackets is not supported. So i was trying to do it other ways

Maybe the answer is it will work if i call gather later?

What do you mean by completed all operations? I am trying to understand the documentation about gather completed work that is qued up essentially but a bit unclear.
