MATLAB: Matrix manipulation and components

MATLABmatrixmatrix arraymatrix manipulation

Hi guys, I have a matrix A=random('norm',3,0.2,100,100) in which I want to display all the components that are >3.1 can someone help me out please 🙂

Is this what you're asking for?

A(A>3.1)

%your matrix is M
isBetween = (M >= 2.9) & (M <= 3.2);
M(isBetween) = -1

A=random('norm',3,0.2,100,100)
A(:,2:2:end)=ones(size(A(:,2:2:end)))
