if i have a (n,m) matrix A and i want to check condition if true then copy this row or column to new matrix?
A = [ 1 1 1 0 0 0 0 0 1 1
1 1 0 0 0 0 0 1 0 1
1 1 0 0 0 0 0 1 0 1
1 1 0 0 0 0 0 0 0 1
1 1 1 0 0 0 0 0 1 1
1 1 1 1 0 0 0 1 1 1
1 1 1 1 1 0 1 1 1 1 ]
the condition is if there a row or a column
* if the row or the column have a group of one with one zero between them
* if the number of zero in this row or column < number of ones in this row
if this two condition true then copy this row or column to new zeros matrix

A = [ 1 1 1 0 0 0 0 0 1 1
1 1 0 0 0 0 0 1 0 1
1 1 0 0 0 0 0 1 0 1
1 1 0 0 0 0 0 0 0 1
1 1 1 0 0 0 0 0 1 1
1 1 1 1 0 0 0 1 1 1
1 1 1 1 1 0 1 1 1 1 ]
[n,m]=size(A)
s=sum(A,2)
for k=1:n
idx(k,1)=~isempty(strfind(A(k,:),[1 0 1]))
end
ii=s>m/2 & idx
out=A(ii,:)
