Remove missing entries from nested cell array

Hello,

I have a cell array which has string arrray inside like for example below:

and some of the string array have empty/missing contents:

I would like to remove these empty/missing entries from the overall cell_array (temp_vars).

I tried something like:

temp_vars = temp_vars(~cellfun('isempty',temp_vars))

but did not find a solution yet. Any help would be appreciated.

temp_vars = temp_vars(~cellfun(@(x) any(ismissing(x)),temp_vars))

Hello @Dyuman Joshi I dont want to remove the entire cell, for example your code removes the temp_vars{1,6} cell completely.

But i want to remove only the first empty empty/missing string in the cell. Basically temp_vars{1,6}(1,2) which is "t_mass_graphic" should be shifted to temp_vars{1,6}(1,1)

@ML_Analyst, As you mentioned overall cell_array, I interpreted it like that.

Nevertheless, in that case -

for k = 1:numel(temp_vars)
    idx = find(ismissing(temp_vars{k}), 1);
    temp_vars{k}(idx) = [];
end

How many does that remove? He wants to "to remove only the first empty".

Thanks for pointing out the mistake, @Image Analyst, I have updated my code.

% make a cell array of string arrays with some missing elements:
str = ["some",missing,"string"];
C = repmat({str},1,3)

C = 1×3 cell array
    {["some"    <missing>    "string"]}    {["some"    <missing>    "string"]}    {["some"    <missing>    "string"]}

% remove the missing elements:
C = cellfun(@rmmissing,C,'UniformOutput',false)

C = 1×3 cell array
    {["some"    "string"]}    {["some"    "string"]}    {["some"    "string"]}
