I am trying to replace even elements in my matrix with zero like below:
a = [3 5 4 1 2]
enter magical code here
a = [3 5 0 1 0]
Any help would be greatly appreciated

"I am trying to replace even elements in my matrix with zero like below:"
a(2:2:end)=0
But the example is different ??
a = [3 5 0 1 0]

a(2:2:end)=0 makes the even indices = 0. I would like to make the even elements = 0.

a(mod(a,2)==0)=0
