I have a character vector ( c = ['a' 'r' 'y' 'z' 'b' 'u' 'k'] ) and I would to determine the number of characters that are not b or r. How do I do this using logical operators?

Note that
c = ['a' 'r' 'y' 'z' 'b' 'u' 'k'];
is just a more complex and less efficient way of writing
c = 'aryzbuk';
You do not need to concatenate individual characters to make a character vector. It is totally superfluous. No experienced user would bother doing this.

Try setdiff()
c = ['a' 'r' 'y' 'z' 'b' 'u' 'k'];
n = numel(setdiff(c, ['b' 'r']));
