     @AbbieNormal It's a typed array of rank 2 of signed 32 bits.

     ah yes it is

     I'm seeing the print of array-A right now 👀

     @AbbieNormal Yes, if it's a conventional array it doesn't show anything. If it's a typed array it shows u8, s32...

     so is #2s32 an ad hoc syntax ?

     @AbbieNormal they are the arguments of the function array-map. You apply the function + on the elements of matrix-A and matrix-B and the result is stored in matrix-C. Sorry, I don't know explain it better. 😅

     and in the call to array-map! the "+" between the first and second argument

     What is that ?

     Is that using postfix syntax ? 👀

     @AbbieNormal The expert on arrays in Guile I think is Daniel Llorens. He's working on https://github.com/lloda/guile-newra , but the API will be more or less the same.

     @AbbieNormal But, without a doubt, Daniel Llorens examples aren't for newbies 😅: https://github.com/lloda/guile-newra/blob/master/examples/maxwell.scm
