How do I slice a Julia matrix so that I get the first x rows?
I've tried
slicedMatrix = matrix[1 : x ; :]
but I keep getting this error
ERROR: LoadError: MethodError: no method matching typed_vcat(::Array{Float64,2}, ::StepRangeLen{Float64,Base.TwicePrecision{Float64},Base.TwicePrecision{Float64}}, ::Colon)
Using commas instead of semicolons doesn't help.

Assuming x
is defined it should just be slicedMatrix = matrix[1 : x, :]
.
