Use the isnan function to detect it and its location. Since this seems to be a homework problem, I leave the rest to you. (If it is not a homework probllem, I will provide a more detailed Answer.)

My pleasure.

Use the find function. See the documentation to understand how to get both the row and column indices.

You could use the fillmissing function to fill the location of your missing data (NaN for double and single precision variables) with a constant. It will also allow you to specify different methods to fill that missing data (several types of interpolation, values that are "around" the missing data, or moving average or median.)
