Hello,

I have an initialized 2D Float array as follows:

`proj_img = zeros(1024,1024)`

I have another 2D Float array contain a specific row and column location as follows:

```
pix_vis_locs= [621 1
622 2
623 3
624 4
625 5
]
```

The first column is corresponding to row location and second column corresponding to the column location of first matrix `proj_img`

. I am trying to update the values of specified indices of `proj_img`

as follows similar to MATLAB:

`proj_img[pix_vis_locs[:,1],pix_vis_locs[:,2]] .= 1`

I expected `sum(proj_img)==5`

but I got `25`

. Then I realized that this method updates all combination of row and columns.

But I need to update values only in above mentioned 5 indices. How can I do that?

Thanks in Advance !!
