matrix - Using fprintf to print on several lines in Matlab -


question: write procedure called print7 print integer numbers within range 0:100 divisible 7. ten numbers printed on 1 output line. hence write program invokes procedure.

this did

 file = fopen('print7.dat','r');   x = 1:100   x=[1:100]    if mod(x,7) == 0;     print7 = [x]  end end  fprintf('print7 %d\n', print7)

now it's output becomes number 98 - understand largest number under 100 divisible 7. want 10xn matrix-like result.

what do?

what doing stores result in variable , overwrites variable in each iteration. print directly instead this:

c=0;  x=[1:100]    if mod(x,7) == 0       fprintf('%3d',x)       c=c+1;       if mod(c,10) ==0         fprintf('\n')       end    end end

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...
