Accessing and using struct array using vectorization
显示 更早的评论
Hello,
I have a cell array structured like this:
list_el =
36×3 cell array
{[ 1 3]} {0×0 double} {0×0 double}
{[ 1 5]} {0×0 double} {0×0 double}
{[ 1 7]} {0×0 double} {[ 3 5]}
...
And I use this loop to extract data to another matrix. I wonder if there is a way using vectorization to do this?
aa = zeros(size(list_el,1),2);
for i = 1: size(list_el,1)
aa(i,:) = list_el{i,1};
end
Thank you!

common would be to use cell2mat(list_el(:, 1)) and assume that function is coded well.

aa = vertcat(list_el{:,1});

This would be more efficient than cell2mat, and can work for some datatype that cell2mat does not support. However it is typically only suitable when the cell is a vector
