Hi! I want to load an unknown amount of tables, and store them in an array, list, or even a matrix.
I tried implomenting it using a simple array, and even a cell array (in which each cell represnets a table), but I always find myself getting errors like "Can't convert from table to cell".
Is there is a way to store multiple tables is some sort of a list?
Thanks in advance!

You can't make an "array of tables" per se, because a table is already an array. But you can put multiple tables in a cell array, as Adam shows. Another option (if they are similar enough) is to vertcat them and add a variable that says which "chunk" of data each row is from. Things like groupsummary and varfun can work with a format like that, using the new variable as a "grouping variable".

Hi.
I think you are using smooth parenthesis for assigning table to cell index i.e. c(1)=Table which results in "Can't convert from table to cell".
Try changing parenthesis to curly braces i.e. c{1}=Table
For loading unknown amount of tables you can iterate over each table and assign them inside cell dynamically.
