Eliminate Nan row in a large matrix

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!
