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.

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

% 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"]}
