how to get character from an array using another logical array?
for example
V = '1b.%291x g'
'yig&aaSgwa'
'tqtbbs!?R!'
logicalVec = [ 1 0 1 0 1 0 1 0 1 1; 0 1 1 0 1 0 0 0 1 1; 1 0 1 0 0 1 1 1 0 1]

A slight modification on your inputs:
V = ['1b.%291x g'; 'yig&aaSgwa'; 'tqtbbs!?R!'];
logicalVec = logical([ 1 0 1 0 1 0 1 0 1 1; 0 1 1 0 1 0 0 0 1 1; 1 0 1 0 0 1 1 1 0 1]);
You can then use a logical index to find the characters corresponding to true values:
V(logicalVec).'
