I have a matrix 20X1. I want to read all the elements of c2 and put the condition as if element of c2 is greater that zero and less than 70 then display that element else return. how should I do?

c2 =

    [ 1.3589]
    [ 7.9773]
    [28.2728]
    [28.2728]
    [ 0.8705]
    [ 7.4681]
    [28.2728]
    [37.0303]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]
    [      0]

@Sachin Patil: actually it makes it harder for us to help you when you ask the same question in multiple locations. Then we cannot keep track of your information and explanations, and also what answers you have been given.

Answer 1

[Thorsten]

for i = 1:numel(ca)
  if ca{i} > 0 & ca{i} < 70
   % do this
  else
   % do that
  end
end

If you just want to extract the elements that fulfil the condition:

First remove the empty elements:

 ca2 = ca(~cellfun(@isempty, ca))

Next use logical indexing to pick the elements from ca2:

 cell2mat(ca2(cellfun(@(c) 0 < c & c < 70 , ca2)))
