I need to modify the above matrix in such a way that every row and column should contain atleast one non zero value.
The original matrix you showed already did satisfy this requirement.

the values can be removed under the condition that every row and column should contain atleast one non zero values.

This removes elements until your matrix is no longer valid according to your rule. It is very slow for bigger matrices, but it is guaranteed to work. Look up "bubble sort" if you want to understand how it works.
A=rand(4,8);
isValidMatrix=@(x) all(any(x,1)) && all(any(x,2));
B=A;
%use a structure similar to the 'bubble sort' algorithm
for idx1=1:numel(B)
for idx2=idx1:numel(B)
if B(idx2)==0,continue,end
B_temp=B;
B_temp(idx2)=0;
if isValidMatrix(B_temp)
B=B_temp;
end
end
end
disp(B)
