How to perform the following commands?

How to perform the following commands:

result1 = m(:,abs(m(2,:))< threshold ); .......... This line I want to exclude zero value also.(I mean if it zero ignore it and look at the next value)

[~,idx] = min(abs(result1(1,:))); ....... This line I want to exclude zero value also. (I mean if it zero ignore it and look at the next value)

[Walter Roberson]

result1 = m(:,m(2, :)~=0 & abs(m(2,:)) < threshold );

[M]

@Walter Roberson, what about the second line" [~,idx] = min(abs(result1(1,:))); "

I want to exclude zero value also from this, I mea take the next abs(min value) after zero?

[Walter Roberson]

create a temporary vector that is abs() and replace 0 values with nan and min() that.

Or loop.

Answer 1

[Walter Roberson]

temp = abs(result1(1,:));
temp(temp==0) = nan;
[~, idx] = min(temp) ;
