Adding a space into an array of string

words={'Everything';'is';'theoretically';'impossible,';'until';'it';'is';'done.'};

[rownum,~]=size(words);

words_array=char(words);

[~,colnum]=size(words_array);

sentence=strings(1);

TF=ismissing(words_array);

i=1;

j=1;

while j<colnum+1 && i<rownum+1

temp=words_array(i,j);

sentence=sentence+temp;

if TF(i,j)==1

i=i+1;

j=1;

elseif j+1>colnum

i=i+1;

j=1;

else

j=j+1;

end

end

I have to create an string array that puts the words provided together into a string array.

So expected output of this code is

'Everything is theoretically impossible, until it is done.'

In a 1X1 string array.(here I have used the variable 'sentence')

However, this code does not provide spacing between the words for the elseif statement.

The current output of the code above is

'Everything is theoreticallyimpossible, untill it is done.'

I need to add a space into the variable sentence when my else if statement holds true.

So far, I have tried

elseif j+1>colnum

i=i+1;

j=1;

sentence=sentence+'';

But this does not work.

How do I add a space to the variable sentence under else if statement?

words = {'Everything';'is';'theoretically';'impossible,';'until';'it';'is';'done.'};
out = join(string(words))

out = "Everything is theoretically impossible, until it is done."
