# How I can do? Tsol=(G==0)=Tamb

Asked by Liviu on 19 Nov 2012
```G=[1;0;2;3;0];
Tsol=[11; 12; 13;14;15];
Tamb=[10;15;16;16;12]
Tsol(G==0)=Tamb;
```

if all the variables are only one row it works but when is an array not.

Thanks

This are array: G=[1;0;2;3;0]; Tsol=[11; 12; 13;14;15]; Tamb=[10;15;16;16;12]

The final resultant neet to be: Tsol= 11 15 13 14 12 in stead of 11 12 13 14 15 the 12 and 15 are change and comes from Tamb

Those are 1D vectors, not 2D arrays. Matt's solution will work fine on them. I don't know why you said it works with one row - I ran your code and it didn't work (but with Matt's fix it works). How did you get that to work????? In fact I believe Matt's fix should also work for arrays of any dimension since it uses linear indexing.

The solution is: Tsol(G==0) = Tamb(G==0);

No, your example doesn't run and will not generally work for vector input either. However, this might be what you want:

```Tsol(G==0) = Tamb(G==0);
```
