How to get the logical index 1 if the cell is missing?

Hello everybody,

I have the 2x1 cell array and (2,1) is {1×1 missing}.

To get the logical index 1 about data(2,1) missing, I tried

ismissing, isempty, and contains functions but all does not work...

Please let me know how to get the logical index 1 about the cell(2,1) is missing?

clc;        % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;      % Erase all existing variables. Or clearvars if you want.
load input.mat
% I tried below but all does not work 
ismissing(data(2,1))
isempty(data(2,1))
contains(data(2,1),'missing')
% to get the logical index 1 about data(2,1) missing, how to do it...

Answer 1

[Walter Roberson]

cellfun(@(M) any(ismissing(M)), data)

or if you just want to test the one,

any(ismissing(data{2,1}))

Note that missing is a value that can appear as entries in arrays, so it is possible for an array to have some missing entries and some non-missing entries. The above code checks for cells in which at least one entry is missing, but does not report which of the array elements are missing.
