How to get the location/coordinate of a value in the matrix?

I have matrix like this,

Data:

     2     1     4     6     2
     9     4     6     1     4
     5     3     2     8     3
     7     2     1    NaN    3
     7     1     8     2     7

I want to make output where the 'NaN' is located. So from case above, it will be ---> Data(4,4). what can i do to matlab code to produce that output?

Need help soon, Thanks before :')
