Setting certain array elements to 0
显示 更早的评论
Hi everyone, this one is probably pretty simple but I can't seem to figure it out.
I have some matrix let's call it A
if true
A = [ 1, 2 ,-2; 0, 2 ,5; -0.5, 2, 1]
Now i want to set all the values between two specific values to zero, for example the values from 0 to 1. I can set all the values below 1 to 0 quite easily by adding:
if true
A(A<1) = 0
But adding a second inequality into this code doesn't seem to work:
if true
A(0<A<1) = 0
Does anyone have any ideas? Thank in advance John.

You have to separate the individual logical tests:
A((0<A) & (A<1)) = 0
However, since none of your matrix elements meet those criteria, it will be unchanged.
