How to create new matrix in for loop?

I am trying to filter data greater than 0.02 in an existing matrix and create a new matrix with those values. Can someone tell me how to do this?

MATLAB is "MATrix LABoratory" -- it operates on matrices and arrays by builtin syntax; that's a primary source of its power and usefulness. "We don't need no steenkin' loops!" :)

YIELDTHRESHOLD=0.02;            % don't bury magic numbers in code; use variables so can change
DivYieldAboveThresh=DividendYield2019(DividendYield2019>YIELDTHRESHOLD);    % use logical addressing

The above is one of the most powerful addressing features in MATLAB -- look up "logical addressing" in the documentation.
