Hi I have data in MATLAB like this:

```
F =
1.0000 1.0000
2.0000 1.0000
3.0000 1.0000
3.1416 9.0000
4.0000 1.0000
5.0000 1.0000
6.0000 1.0000
6.2832 9.0000
7.0000 1.0000
8.0000 1.0000
9.0000 1.0000
9.4248 9.0000
10.0000 1.0000
```

I am looking for a way to sum the data in specific intervals. Example if I want my sampling interval to be 1, then the end result should be:

F =

```
1.0000 1.0000
2.0000 1.0000
3.0000 10.0000
4.0000 1.0000
5.0000 1.0000
6.0000 10.0000
7.0000 1.0000
8.0000 1.0000
9.0000 10.0000
10.0000 1.0000
```

i.e data is accumulated in the second column based on sampling the first row. Is there a function in MATLAB to do this?

Answer:

Yes by combining `histc()`

and `accumarray()`

:

```
F =[1.0000 1.0000;...
2.0000 1.0000;...
3.0000 1.0000;...
3.1416 9.0000;...
4.0000 1.0000;...
5.0000 1.0000;...
6.0000 1.0000;...
6.2832 9.0000;...
7.0000 1.0000;...
8.0000 1.0000;...
9.0000 1.0000;...
9.4248 9.0000;...
10.0000 1.0000];
range=1:0.5:10;
[~,bin]=histc(F(:,1),range);
result= [range.' accumarray(bin,F(:,2),[])]
```

If you run the code keep in mind that I changed the sampling interval (`range`

) to 0.5.

This code works for all sampling intervals just define your wanted interval as `range`

.
