MATLAB: Assigning multiple variables vectors from a cell array

cell arrayvariablesvectors

I'm wondering if there is any smart solution on how to access multiple same-sized vectors inside of a cell array and assign them to an independent variable.

cellArray =
   1×4 cell array
    {1×101 double}    {1×101 double}    {1×101 double}    {1×101 double}

Thanks!

I would just do the following and then access them using 3rd indices

reshape(cell2mat(cellArray),[size(cellArray{1}) length(cellArray)])

MATLAB: Concatenate arrays within a loop,

Easy, given any number of arrays in a cell array C. You could use a loop like this, although it is inefficient because the output array is not preallocated:

C = {[1,2],[3,4],...} % cell array of arrays.
A = C{1};
for k = 2:numel(C)
    A = [A;C{k}];
end

Simpler and more efficient would be to concatenate them all at once, without a loop, e.g.:

A = vertcat(C{:})

Whatever you do, do NOT try to access variable names dynamically in a loop! Read this to know why:

Using an array (e.g. a cell array) and indexing is much simpler, neater, much more efficient, less buggy, and easier to debug.
