How do I Vectorize the for loop containing if else ?

for j=1:n

for i=1:m

if xH(i,j)>0

X1(i,j)=xH(i,j);

X2(i,j)=xH(i,j);

end

end

end

for j=1:n

COUNTcol=0;

for i=1:m

if X1(i,j)>0

COUNTcol=COUNTcol+1;

end

end

X1 = zeros(size(xH));
X2 = zeros(size(xH));

idx = xH > 0;
X1(idx) = xH(idx);
X2(idx) = xH(idx);

COUNTcol = sum(X1 > 0, 1);
