find all rows in a table which equal nan in matlab

To find all rows in a matrix that contain NaN values in MATLAB, you can use the isnan and any functions together. Here is an example:

main.m
% Sample matrix
matrix = [
    1 2 NaN 4;
    5 NaN 7 8;
    9 10 11 NaN
];

% Find rows with NaN
rows_with_nan = any(isnan(matrix), 2);

% Display the rows with NaN
disp(matrix(rows_with_nan, :));
198 chars
13 lines

Running this code will give you the rows in the matrix where at least one element is NaN. The isnan function returns a logical matrix, where true values represent NaN elements. The any function is then used to find rows that contain at least one true value, indicating the presence of NaN. The resulting logical indices are used to extract the corresponding rows from the matrix.
