Calculating the Pairwise covariance: with NaN's

I am trying to calculate the pairwise covariance.
x=rand(100,36);
TheNaNC=randi([1 100],1,10);
TheNaNV=randi([1 36],1,10);
x(TheNaNC,TheNaNV)=NaN;
c2 = cov(x,'partialrows');
I get the following error message: 'Error using cov (line 64) The number of elements in x and y must match.'
Also tried:
c3 = cov(x,'omitrows');
'Error using cov (line 64) The number of elements in x and y must match.'
What am I doing wrong with this?
I am trying to calculate the covariance the why R calculate it but using MATLAB

The random integers should be drawn between 1 and 100 (1 and 36), not 0 and 100 (0 and 36).
Best wishes
Torsten.
