Imagine that you have a cell array and you want to determine its size. What command would you use for it? Also how do I split the data of the cell array into half. lets say it has 60 rows and and i want it to be split after 30 rows.
thanks

Funnily enough. size is the function to get the size of cell arrays and matrices. If you want to split along rows, either use size or end:
c = num2cell(randi(200, 60, 5));
tophalf = c(1: ceil(end / 2), :); %equivalent to c(1 : ceil(size(c, 1) / 2), :)
bottomhalf = c(ceil(end / 2) + 1 : end, :);

To get the memory footprint of a variable it's whos
c = num2cell(randi(200, 60, 5));
msize = whos('c')
As for splitting:
tophalf = c(1:4, :);
bottomhalf = c(end-56+1:end, :);
