(array-concatenate axis a . o)
Returns a new specialized array which is the concatenatation of 1
or more arrays along the
axis
dimension. All arrays must
have the same dimension, and all domains must have the same width
for each dimension except
axis
.Shorthand for array-permute, swapping two dimensions.
Returns true iff all arrays have the same domain, and all elements
in the same indexes are
=
.
Returns the 2-d identity matrix of size
n
.Performs Gaussian elimination and returns the factor to apply to
the determinant.
Returns the inverse of 2-d array
a
, or
#f
if
a
is not invertible.Computes the determinant of 2-d array
a
, mutating
a
in
the process.
Computes the determinant of 2-d array
a
.Returns a new array representing the matrix multiplication of 2-d
arrays
a
and
b
.
(pretty-print-array a . opt)
Nicely formatted printing for arrays of any rank. Ranks
higher than 2 are represented as successive 2D drawings.
Can generate box drawings with left:, right:, etc. keywords
specifying the strings to use. For example, Jacal-style
matrix output can be done with:
(pretty-print-array a #t 'left: "[" 'right: "]")
and a tic-tac-toe board can be printed with
(pretty-print-array a #t 'line-char: "|"
'top: "-" 'middle-col: "|" center-row: "-")
