Question

I have a cell matrix with two columns (no headers). Column one contains ticker symbols, e.g AAPL, GS etc. Column two contains either 0 or 1.

How can I delete all rows that contain ‘1’ in column 2? Then how can I get an output of the remaining ticker symbols separately in a different m file?

Help please!

Answer 1

Does this do what you need?

>> a = {'AAPL', 1; 'MSFT', 0; 'GOOG' 1; 'IBM', 0} % Make some data like the OP's
a = 
    'AAPL'    [1]
    'MSFT'    [0]
    'GOOG'    [1]
    'IBM'     [0]
>> toDelete = cell2mat(a(:,2)) == 1; % Extract which rows have a 1 in column 2
>> a(toDelete,:) = []; % Delete those rows
>> remainingTickers = a(:,1) % Extract column 1 from the remaining rows
remainingTickers = 
    'MSFT'
    'IBM'
