Operations on matrixes

[C. Arel]

Hi all,

I am trying to modify elements in a matrix that I created with (def the-matrix (matrix 1000 3)) .

I know that I can do the most operations with ($= the-matrix operator other-matrix).

The problem is that I have a seq of elements that corresponds to the matrix but can't figure out how to loop and add from the seq.

I have tried with (for [x seq] ($= the-matrix + x)) but it keeps freezing my repl. 

So it looks like this but with fewer elements in the colllections.

matrix = [0.0 0.0 0.0]  

seq = (23.33 333.3  9898.0)

How can I put the values from the sequence into the matrix??

Thanks,

Just give the seq as the argument to the matrix-function, like this

(def m1 (matrix the-seq))

(def m1 (matrix '(23.33 333.3 9898.0)))
#'incanter.main/m1
incanter.main=> m1
[  23.3300
 333.3000
9898.0000]
