How do you set entries in a matrix for odd rows with odd columns to zero?

I want to set A(i,j) = 0 if both i and j are odd. Is this possible to do vectorially?

%random data for example
A = rand(6,7)
A = 6×7
0.5610 0.2871 0.6280 0.3569 0.2765 0.5197 0.9541 0.3110 0.6573 0.3447 0.8105 0.0255 0.8263 0.2238 0.1450 0.6944 0.2345 0.6517 0.8826 0.6646 0.2389 0.0189 0.9227 0.6658 0.1392 0.9954 0.4346 0.1812 0.2084 0.3130 0.1589 0.8685 0.6272 0.6153 0.3176 0.9900 0.3501 0.1301 0.0931 0.5342 0.8533 0.5644
A(1:2:end,1:2:end)=0
A = 6×7
