Matlab got this wrong: Limit as n goes to infinity: (1+(i/n))^(n^2). Matlab says it's exp(2), which is wrong. Pls confirm.
I recommend consulting technical support. It's probably a bug.

Operator '+' is not supported for operands of type 'function_handle'.
Only symbolic functions can be added directly. You may need to refer to Symbolic Math Toolbox.

I have data for each milli second. How can I average the 1000 samples and convert in to 1 sec? I got 322 sec data. 1K samples for each second.
You may want to use imresize： Table=readmatrix('ms_to_sec.csv'); Table=imresize(Table,[322,2]); Table(:,1)=1:322;
