I exported a matrix from my 50g to the PC using Conn4x and this is the result:
[[ 1 2 ]
[ 3 4 ]]
So if you can create such a file from your data, you are fine.
Note that if the data includes any "decimal point", for the ASCII
transfer header, use F(.) if the "fraction mark" is a period, or
F(,) if the fraction mark is a comma.
For that matter, if you omit the transfer header, then the
calculator will store the entire data stream as a character
string, which you could recall to the stack and "execute" with
STR\-> or OBJ-> to get the matrix.
For more information on transfer headers, search from
For the 49 series, numbers without decimal points are compiled as
"exact integers" if the calculator is in "exact" mode, or "real
numbers" if the calculator is in "approximate" mode.
But I do prefer Cristoph's suggestion of using Emu48 to work with
data that's available on the PC, rather than transferring it to a
