Hi all.

I have this array that was a lot info on it. Some of the cells in the matrix are "#undef "

I want to write the file to ascii… any way to change all the #undef to zeros, or something?

Thanks!

you can achieve this by initializing the matrix to be all zeros instead of trying to find and replace `#undef`

. How did you obtain such a matrix to begin with?

Something like this?

```
for i in eachindex(x)
if !isassigned(x, i)
x[i] = 0
end
end
```

you might want `zero(eltype(x))`
