midpoints

midpoints(e)

Compute the midpoints of the bins with edges e. The result is a vector/range of length length(e) - 1. Note: Julia does not ignore NaN values in the computation.

Examples

In the Julia programming language, the function midpoints(e) calculates the midpoints of the bins defined by the edges e. The resulting vector or range has a length of length(e) - 1. It's important to note that Julia does not ignore NaN values in the computation.

Calculate midpoints of bin edges:
```
julia> edges = [0, 2, 4, 6, 8];
julia> midpoints(edges)
4-element Array{Float64,1}:
1.0
3.0
5.0
7.0
```
This example calculates the midpoints of the bins defined by the edges [0, 2, 4, 6, 8].

Compute midpoints using a range:

julia> edges = 0:2:8;
julia> midpoints(edges)
4-element StepRangeLen{Float64, Base.TwicePrecision{Float64}, Base.TwicePrecision{Float64}}:
1.0
3.0
5.0
7.0

It computes the midpoints using a range for the bin edges.

Handling NaN values:
```
julia> edges = [0, 2, NaN, 6, 8];
julia> midpoints(edges)
3-element Array{Float64,1}:
NaN
NaN
7.0
```
It shows that NaN values are not ignored in the computation, resulting in NaN midpoints.

Common mistake example:

julia> edges = [0, 1, 2];
julia> midpoints(edges)
ERROR: DimensionMismatch("arrays could not be broadcast to a common size")

In this example, the length of the resulting vector would be 2, but the provided edges have a length of 3. The number of edges must be one more than the number of midpoints.
