Hi,
I have a string array like this:
x=[Na,Mg,Si ; V ; Na,Mg,Si,S ; Si ; Na,Mg,Al,P]
I want to delete all the rows which contain just one Value. Does somebody has an idea how it could work? Because I reached my limit of knowledge (really new in matlab).
I appreciate any idea :-)

Yes, the string array just contains Elements as string variables. The problem is that they change from sample to sample, depends on the sample. Sometimes the elements stands alone in a row, but also in rows with other elements, so I cant just delete the elementname. I need a solution to general delete rows with just one value. I hope you understand what I mean.

Ran in:
as i don't have your data so i have added NaN string to make the same dimension cell array
x={'Na','Mg','Si' NaN; 'V' NaN NaN NaN; 'Na','Mg','Si','S' ; 'Si' NaN NaN NaN; 'Na','Mg','Al','P'};
a=string(x);
y=rmmissing(a,1,'MinNumMissing',2);
output=cellstr(y)
output = 3×4 cell array
{'Na'} {'Mg'} {'Si'} {0×0 char} {'Na'} {'Mg'} {'Si'} {'S' } {'Na'} {'Mg'} {'Al'} {'P' }

~ supposed to mean not.
~= menas not equal.
isequal function returns empty cell. so ~ which is used before isempty fucntion returns not empty cell
