Thread Subject: about sprintf.

hi all;

What can i put in my program to know : how often does
message('valid characteristics of the region number%d')
appear?

my program is:

for j=1:10,
if T(:,j)==1%% size of T is=5*10
sprintf('valid characteristics of the region number%
d ',j),
end
end


Thanks.

one of the solutions

% the data (4x2 for sake of brevity...)
     t=[
          1 2
          2 2
          1 1
          2 1
     ];
% the engine
% - any col contains a <1>
     ix=any(t==1,2);
     sprintf('valid region %d\n',find(ix))
%{
     ans =
     valid region 1
     valid region 3
     valid region 4
%}
% - all col must contain a <1>
     ix=all(t==1,2);
     sprintf('valid region %d\n',find(ix))
%{
     ans =
     valid region 3
%}

Hi us;

Thanks for your answer but you don't undersand what i
mean; so as your exemple i want to obtain a variable x
which contain number of sentences "valid region "

i remenber your exemple :

 t=[1 2
    2 2
    1 1
    2 1];

 ix=any(t==1,2);
     sprintf('valid region %d\n',find(ix))

ans =
     valid region 1
     valid region 3
     valid region 4



so, my question is: how can i obtain auomatically when
executing this program, x=3 (we have three sentences in
this case)?

Either follow the solution you were given yesterday
(the one using the counter named n), or else make the entire
section of code into a quoted string and use evalc() to evaluate
the code and then find the size of the captured output.

well, what about

     ns=sum(ix)
% ns = 3
