linalg::matdim
-- dimension of a
matrixlinalg::matdim
(A)
returns the dimension of
the matrix A, i.e., the number of rows and columns of
A.
linalg::matdim(A)
A |
- | an m x n matrix of a domain of category
Cat::Matrix |
the list [m, n]
, where m
is the number of
rows and n
is the number of columns of A
.
linalg::vecdim
,
linalg::ncols
, linalg::nrows
linalg::matdim
is an interface function for the method
"matdim"
of the matrix domain of A
, i.e.,
instead of linalg::matdim
(A)
one may call
A::dom::matdim(A)
directly.The dimension of the matrix:
>> A := matrix([[1, 2, 3, 4], [3, 1, 4], [5, 6]])
+- -+ | 1, 2, 3, 4 | | | | 3, 1, 4, 0 | | | | 5, 6, 0, 0 | +- -+
can be determined by:
>> linalg::matdim(A)
[3, 4]
