hi! I am extracting the fields of a structure using the following code
names = fieldnames(BD);
for ii = 1: length(names)
eval([names{ii} '=BD.' names{ii}]);
end
and it works but I get all the extracted arrays and data shown in the commend window also, any suggestion how to avoid this ?! thank you!

Do NOT use eval for such trivial code. This way of accessing structure fields has been obsolete for more than ten years, as you will learn when you read the MATLAB blogs.
Use dynamic fieldnames instead:
names = fieldnames(BD);
for ii = 1:numel(names)
names{ii} = BD.(names{ii});
end
Or learn how to use MATLAB efficiently and use struct2cell:
out = struct2cell(BD);
