Here is an old patch I found on my drive that still stand (I can't find a way to do pull request without forking clem in github and I don't want that for such a simple patch):

Hello,
I have some problems with matrices with complex values.
The problem seems caused by some type coercion, for example if I want define a complex matrix like this:
(defun matrix-test-1 ()
(let ((m (array->complex-matrix #2A((#c(1 1) #c(2 0) #c(3 1))(#c(4 1) #C(0 1) #c(0 6))(#c(7 1) #c(0 1) #c(9 9))))))
(print-matrix (m+ m m)))
t)
I got an error because 2 is not a complex value, but #c(2 0) is a legit complex value with no imaginary part.
I have a similar problem with #c(0 1) (the pure imaginary unit), because if some operation (like m.*) involves this kind of multiplication #c(0 1) * #c(0 1), I have the same error about -1 (the result of i^2) because it says it's not a complex value.
Please could you analyze this behaviour ?
thanks,
Fausto
