MATLAB: What are the differences between [] and ” in a cell array, how to identify and differentiate them

Question

c1={'a',[],'b'}–>

isempty(c1(2))=0; Not empty

size(c(2))=1 1;

strcmp(c(2),[])=0; Not a string

c2={'a','','b'}–>

isempty(c2(2))=0; Not empty

size(c(2))=1 1;

strcmp(c(2),'')=1; Is a string

So I can use strcmp(c,'')==1 to find ''. But how about []?

Thanks…

Answer 1

isempty(c1{2})

Notice the {} instead of ()
