You could do this with two calls to conv2():
A=[1 0 1];
V=[1 1 1 1 1 0 0 1 1 0 1];
small_matrix = A;
big_matrix = V;
xbig = logical(big_matrix);
xsmall = logical(small_matrix);
Xmorethan80 = (conv2(double(xbig),double(xsmall),'valid')+...
conv2(double(~xbig),double(~xsmall),'valid')) > (numel(small_matrix)*.8)
I do not get the error you are describing with the above.
