Take minimum and maximum of columns for a 1x31 cell

I have a cell array psdMonth that is 1x31, with each cell a 1x114 int 32. I would like to take the minimum of all of the columns of each cell to get a composite minimum that would be 1x114 int 32. So I would want the minimum of psdMonth{1}(1)......psdMonth{31}(1), and then the minimum of psdMonth{1}(2)....pdMonth{31}(2), etc.

I had tried something like this:

     minpsdMonth = min(cat(1,psdMonth{:}))

which does create a 1x114 int32, but I'm not sure how to test if it's actually doing what I think it should. Can anyone tell me how I would get the output I want? Or verify that what I am doing is correct?

Thanks!

• your solution looks ok to me
• test with some synthetic data, the results of which you know

It looks to be doing the right thing for my synthetic test

    c={ [10 35 45 55 67] [45 55 65 76 86] [55 58 59 90 1] };

       min(cat(1,c{:}))

      ans =

    10    35    45    55     1

Thanks for the simple advice. Sometimes when you're beating your head against the wall about something it's good to be reminded.

"integers or only doubles" Here, I trust Matlab. If it doesn't issue an error it should be ok.

A little test

    >> c={int32([10 35 45 55 67]),int32([45 55 65 76 86]),int32([55 58 59 90 1])};
    >> min(cat(1,c{:}))
    ans =
              10          35          45          55           1
