Asked by subha

i want to verify each element in the matrix and keep that value in the same place if its true otherwise i want to make it as 0.

example: say x=[0.1 0.2 0.3;0.4 0.5 0.6;0.7 0.8 0.9]

i want to check two condition 1.Y=x>0 &x<0.25 2.Z=x>0.25 & x<0.5

i want both Y and Z to be in same size.so,want to add zeros in all the other locations where condition is not satisfied.Can anybody help?

i used ind=find(x>0)&(x<0.25) and then y(ind). but it produces an array.how to get matrix of size x with added zero in remaining all places.

Accepted answer

Here's one way:

ind = (x>0)&(x<0.25);

y = ind.*x;

x=[0.1 0.2 0.3;0.4 0.5 0.6;0.7 0.8 0.9] y=zeros(size(x)) z=y; idy=x>0 & x<0.25 idz=x>0.25 & x<0.5 y(idy)=x(idy) z(idz)=x(idz)
