Finding and removing NaN values in a matrix

Hi Guys,
I am dealing with matrices of the size 1268*100. I wish to eliminate certain rows from this matrix. I do certain operations to get integer values for the rows that I want to keep and NaN value for the ones I dont. How can I get the rows that have NaN values and use these numbers to eliminate the rows that I dont want in my main matrix.
Eg. if my column matrix has the following values= [1 2 3 NaN 3 4 NaN 5 7 NaN]
So I will need to eliminate rows 4 7 and 10 in my main matrix.
How do I go about doing that.
Thanks, Nancy

Is it only necessary to refer to column 1, or are there other columns that might have nans that signal removal ?
If column 1 alone is enough, then you can use
values(isnan(values(:,1)),:) = [];

Ahmed, that has the same problems I described for Shubham Maurya's suggestion.
