Replacing numbers in a row

Dear all,

I have a question, I want to try to replace values in a row that are greater than zero. For example, I have the array A that is:

A = [ 0 0 3 5 6 4 0 0 0 3 0 0 3 2 0].

What I want is to replace all values greater than 0 by 1.I know I can use A(A>0)=1 but I don't want to replace the individual 3 by 1 instead I want it to be zero.

I want my result to be:

A = [ 0 0 1 1 1 1 0 0 0 0 0 0 1 1 0]....instead of A = [ 0 0 1 1 1 1 0 0 0 1 0 0 1 1 0].

Is there any way I can do this and specify what individual number I don't want to replace by 1??

Thank You!!

Looks like you're still replacing the first 3. Is that correct?

[James Tursa]

So, can you tell us the explicit rule(s) for the replacement instead of us having to guess at it?

[Bosong Lin]

I guess you are looking for a pattern like in A, '0 3 0', you would like to replace this '3' by '0' also.

I Bosong Lin is right...The number 3 that stands alone in 0 3 0 pattern..I would like to replace by 0 otherwise it would be 1 like the rest of the values

[Guillaume]

So is it just the 3 that stand alone that are not to be replaced, or any number that stand alone?

[John Doe]

Just the 3 that stands alone

Just the 3 that stands alone

result = strrep(A,[0,3,0],[0,0,0])>0;

Thank you!!

A( strfind(A, [0 3 0]) + 1) = 0;
