Find NaN elements in a matrix (X,Y,Z)

Hello.

i,m a new Matlab user and trying to find the closest value to Z in my matrix (se the table blow )and got many problem.

tried to find out a value at the time with

"y_lookup = interpl (X,Y,-----)" but the result was not right one.

Can someone explain the goodway to findout / generate NaN value in my matrix?

and how to interpolate it and replace the NaN?

X=[ -1 :  0.1  :  1]
Y= [-1 :  0.1  : 1 ]
Z = [ 17.46   12.62  12.01  11.68  6.39  13.09   2.64   1.15   NaN   NaN  NaN  NaN NaN  NaN  -1.3  NaN -6.9  NaN  0.9  -0-6]  

Thanks

How does this Z vector correspond to you X and Y? Usually, this would mean you have a surface, with a Z value for each combination of X and Y, which would mean 100 points, not 20.

Yes, thats right . Z value becomes a combination of x and y which going to be the 100 different value .
