Remove or set a row to 0 when containing NaNs

Hi everyone,

I have an array like this:

tnCT =
    3.0070    NaN
   18.0067    3.4871
   34.0071    4.6240
   48.0062    4.9370
  138.0044    5.9247
  153.0041    6.6163

I want to set to 0 the row that has NaN on it. I have tried the following:

    for i = 1:length(tnCT)
      if isnan(tnCT(i,:))
         tnCT(i,:) = 0;    
      end
    end

So I will end with:

tnCT =
         0         0
   18.0067    3.4871
   34.0071    4.6240
   48.0062    4.9370
  138.0044    5.9247
  153.0041    6.6163

Can you please tell me what is wrong with my approach, since it doesn't work? Removing the values also would do the trick (since in the next step I create a nonzeros matrix)

mask = any( isnan(tnCT), 2 );    %find rows with nan
tnCT(mask,:) = [];    %delete them

This did the job, thank you very much!
