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 :-)

are Na,Mg,Si string variables?

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.

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'     }
