Hi, I have a 1x1 matrix. I would like to use the value in it but not as a matrix, any idea how I should take away the matrix and just take the inner matrix? Please help. Thanks.

For example instead of [8x+3], i would like it to be just 8x+3



Hi, I wrote a set of codes that worked perfectly fine 2 months ago, but when I try to run all my files again, this statement came out :


"Error, Got internal error in Typesetting:-Parse:-Postprocess:"intercal error:invalid object""

Could someone please explain what is the meaning of this please? Thanks

Hi, may I know how do i rearrange the matrix by shifting them please?

For example, i have a 9x9 matrix. I would like to shift the first column to the end (1..9,1) becomes (1..9,-1), and the rest of the matrix (1..9,2..9) becomes (1..9,1..8).

Please help. Thanks.
