Cell array values and words.

Want to find which colums contains only B's

a = {

1 'B' 2 'B' ;

'B' 'B' 'B' 'B' ;

1 2 'B' 'A';

}

Wanted outcome:

b =[0;1;0]

This is a simplified version of the entire array a.

Use strcmp or strcmpi along with all.

Template:

all(strcmp(a,'B'),1) % for columns
all(strcmp(a,'B'),2) % for rows
