matlab - Is there a performance difference between array and matrix operators? -


i have several m files wrappers long, complicated equations of sort take more 1 line in journal article. currently, use matrix operators, ie *,/,^. convert them array operators, ie .*,./,.^ can vectorize calculations them.

my question is, there reason couldn't search , replace , change of operators? there performance issue multiplying scalars element-wise operators?

i not matter of performance.

if dealing linear algebra expressions, not want search & replace: suppose a = [1; 2; 3] , b = [4; 5; 6] , have a'*b, cannot convert a'.*b because dimensions not consistent element-wise product (it error).

in case of scalar multiplication, think jit smart enough consider 1*2 , 1.*2 equivalent , interpret them identically.

c# - DetailsView in ASP.Net - How to add another column on the side/add a control in each row? -

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
