Here's code that creates an example cell array for this question:
mycell = cell([5,1]);
for i = 1 : size(mycell)
mystruct = struct();
mycell{i} = mystruct;
mycell{i}.field1 = i;
end
I expected mycell{:}.field1
to do what I want, but it gives an error. I can use the following for loop:
for i = 1 : size(mycell)
mycell{i}.field1
end
but I'd prefer a simpler or more elegant solution as a want to use all the elements of mycell.field1 as the y-variables in a plot. Any ideas?
If all the structs in your cell array have the same fields than you can:
mycell = [ mycell{:} ]; % convert cell array to struct array
y = [ mycell(:).filed1 ]; % get the values
Another method uses cellfun
y = cellfun( @(x) x.field1, mycell );
assuming all mycell{ii}.filed1
are scalars, otherwise you'll need to add 'UniformOutput', false
to the cellfun
.
note: in case some fields are empty ([]
) these methods might not work as expected.
One small remark:
it is not a good practice to use i
and j
as variables in Matlab.
