Referring to specific input in loop

2 views (last 30 days)
I am writing a function and the input arguments are Data1 Data2 Data3 Data4 .... DataN. I am running a loop from i=1:N and one of the commands in this loop is to get the size(Datai) but im not sure how to refer to the specifc Data matrix based on the value of i in the loop.

How/ Why there is Data1, Data2, ...DataN?
This is not allowed/ comfortable. Rather use Data{1}, Data{2},.....Data{N}. This is called cell.

"...the input arguments are Data1 Data2 Data3 Data4 .... DataN."
Numbering variable names like that is a sign that you are doing something wrong.
Most likely your code would be simpler and more efficient if you just used one container array, e.g. a cell array.

If you want to have variable number of arguments, perhaps you want to use varargin instead in your function signature.
function out = f_take_n_args(varargin)
for i = 1:length(varargin)
Datai = varargin{i};
end
end
