i have a velocity matrix of 98x124 and i want to remove the complete row where the velocity value is NaN, so that afterwards i can take the mean of the matrix. How can i delete it?

X(4,2) = NaN;
[I,J] = find(isnan(X));
X(I,:) = [];

X = randn(98,124);
X(4,2) = NaN;
[I,J] = find(isnan(X));
X(I,:) = [];
