How to store multiple arrays into a single one?

85 visualizzazioni (ultimi 30 giorni)
array_1 = zeros(1,9);
array_2 = zeros(500,16);
With the increase in time I will be concatenating arrays one and two into array3. I tried it by doing this:
array_3 = [array_1,array2];
Since, they are not from the same size, they can´t be concatenated.
Any ideas on how can I save them?

"Is it better to use an cell array or an structure?"
It depends entirely on what you are doing:
  • if your data have an inherent sequence, then use a container array which can be accessed using indices (e.g. cell array, non-scalar structure, table rows).
  • if your data are best identified by parameter names, then use a container array which lets you use names (e.g. structure, table columns).
Use the simplest data type that can reasonably hold your data, as this will simplify your code.

How to initialize the cell array?
function y = (input,vector)
persistent count
persistent array_3
persistent array_2
persistent array_1
persistent Matrix
if isempty (array_3)
array_3 = cell(1000,2);
%array_3 = cell(repmat({zeros(1,9)}, 100, 1),repmat({zeros(1,9)}, 100, 2));
count = 0;
array_1 = zeros(1,9);
array_2 = zeros(500,16);
Matrix(1:500,1:15)= data;
Matrix(1:500,16)= input;
%Look through the data
peak = find(Matrix(:,16)== 1);
val = length(peak);
if val > 5
Counter = Counter + 1;
array_3{Counter,1} = array_1;
array_3{Counter,2} = array_2;
y = array_3;
Simulink does not have enough information to determine output sizes for this block. If you think the errors below are inaccurate, try specifying types for the block inputs and/or sizes for the block outputs.

Cell arrays as top-level function outputs are not supported in MATLAB Function Block. Output 'Output' is a cell array.
