how to find smallest number among 10 numbers in a if loop?

Hi all I need find the smallest number among 10 numbers using if loop or for loop.Please need help.

There is no such thing as an "if loop". "if" executes the body exactly 0 or 1 times, which is not a loop; "for loop" and "while" (usually) execute multiple times.

Try this:

minValue = inf; % Initialize to infinity
for k = 1 : 10
  if array(k) < minValue;
    % Surely you can fill in the rest!
  end
end

It's probably too much of a hint but it's hard to do much less since it's so short and trivial.

Thank u sir...Please reply for my work.I just have some linelengths as given below

linelen3=l3;
linelen4=l4;
linelen5=l5;
linelen6=l6;
linelen7=l7;
linelen8=l8;
linelen9=l9;
linelen13=l13;
linelen14=l14;
linelen15=l15;
linelen16=l16;

Now i want to find which lines length is the shortest. I tried as

shortestline=linelen3;
linenum=3;
for k=4:16
 if linelen(k)<shortestline
   shortestline=linelen(k);
   linenum=k;
 end
end

Please tel me wat mistake i did...

Remove the semicolons from the end of your sentences and see the results of each line.

Calling a variable "linelen5" is a bad idea and a standard mistake of beginners. Use an array instead: "linelen(5)" etc.

[Image Analyst]

linelen = [13, 14, 15, 16, 17, 18, 19, 113, 114, 115, 116]
shortestline = linelen(1)
for k = 2 : length(linelen)

etc.
