There is an instance where you have echotime * scalar
:
Line 209 in e64a43f
.*
.
There is also an instance of echotime * vector'
:
Line 228 in e64a43f
echotime*df'
with outerproduct(echotime, df)
, and then have
outerproduct(echotime::AbstractArray, df) = echotime*df'
outerproduct(echotime::Tuple, df) = [TE * df for TE in echotime, df in df]
With the current definition of Echotime
, one can't pass in a Tuple
with various element types, so, e.g., (0, 2.3)
will throw an error. This is because of the <:
in NTuple{N,<:T}
; removing <:
would allow for (0, 2.3)
.
Not sure if you intended to force all the types of the Tuple
elements to be the same, but if not, it should be an easy change.
