Hello,

I have following vectors tmvalues and Zimfi. I am finding Yvalues vector by using those two and finding the following answer.

    tmvalues - Zimfi   = Yvalues
       12        0         12
       11        0         11
       10        6          4
       12        0         12 
       11        3          8
       10        0         10
       12        0         12
       11        5          6
       10        0         10

Then, to print Yvalues with its title, I am using the following code (i=m=3) and having the following output:

[Y1,Y2] = meshgrid(1:i,1:m);

Ytitle = [Y1(:),Y2(:),Yvalues(:)];

fprintf(' Y%d%d %d\n',Ytitle.')

However, I don't want to print the rows of Yvalues answer, where Zimfi element is 0. So, I actually want to have this result.

   Y13     4
   Y22     8
   Y32     6

How can I eliminate the rows of Yvalues which of its Zimfi element is 0? Sorry for writing so long. I wanted to make it as clear as possible. I really appreciate for your answers.
