How to eliminate string array elements by passing binary array

Question

0 个投票

Hello,

I have an array of strings that I would like to manipulate with a secondary binary array. Something like

if true
  myStrings = {'Title1','Title2','Title3'};
  seconaryArray = [1,0,1];
  a = myStrings * secondaryArray;
end

The output I desire from this example is

a = {'Title1','Title3'}

but the error I am receiving is

Undefined function 'mtimes' for input arguments of type 'cell'.

I hope someone can help me with my syntax problem.

Thank you,

Geoff
