Hello,
I have a very large matrix where some elements are Nan.
I would like to delete the rows containing the these elements.
Example
For
A=[1 2 3; 2 4 Nan; 4 5 6; nan 9 0];
Output:
A=[1 2 3];
Any ideas?
Thank you

A(any(isnan(A),2),:) = [];

Hi ,
I understand that you want that eliminate NaN rows in the matrix,we can achive this with help of ‘isnan’ function.
Here is the code example:
A = [1 2 3; 2 4 NaN; 4 5 6; NaN 9 0];
% Find rows with any NaN values
rowsWithNaN = any(isnan(A), 2);
% Keep only rows without NaN values
A = A(~rowsWithNaN, :);
% Display the result
disp(A)
1 2 3 4 5 6
Hope it helps!
