I would like to take a matrix that is currently made of bools and turn it into floats.

If `I`

is this matrix of bools, I’ve been trying commands like `convert(Int8, I)`

and getting errors like

```
ERROR: MethodError: Cannot `convert` an object of type Matrix{Bool} to an object of type Int64
Closest candidates are:
convert(::Type{T}, ::T) where T<:Number at number.jl:6
convert(::Type{T}, ::Number) where T<:Number at number.jl:7
convert(::Type{T}, ::Base.TwicePrecision) where T<:Number at twiceprecision.jl:273
```

What actually works if I want to be able to do arithmetic operations like matrix multiplications, log etc on an indicator matrix originally made from bools?

I really just want to one-hot encode a vector.

So I’ve been doing something like

```
using StatsBase
v = [1 2 3]
I = indicatormat(v)
```

But then the issue is that the code I have written to run matrix decomposition on `I`

says things like "There are no methods matching what you want to do, and it objects to the fact that my first entry is a `::LinearAlgebra.Transpose{Bool, Matrix{Bool}}`

when it wants a `::Matrix{<:Real}`
