Rows of a matrix#

ctx.mat_rows(matA)#

Returns the number of rows of the matrix. Writing matA.rows has the same effect.

>>> from xlcalcnet import *
>>> mpm.dps = 15;
>>> A = ctx.read_from_sqlite(mp14.dbpath(), "DecTableA6x4", "")
>>> print("A.rows: ", A.rows)
A.rows: 6

Columns of a matrix#

ctx.mat_cols(matA)#

Returns the number of columns of the matrix. Writing matA.cols has the same effect,

>>> from xlcalcnet import *
>>> mpm.dps = 15;
>>> A = ctx.read_from_sqlite(mp14.dbpath(), "DecTableA6x4", "")
>>> print("A.cols: ", A.cols)
A.cols: 4

Size of a matrix#

ctx.mat_size(matA)#

Returns the size of the matrix. Writing matA.size has the same effect.

>>> from xlcalcnet import *
>>> mpm.dps = 15;
>>> A = ctx.read_from_sqlite(mp14.dbpath(), "DecTableA6x4", "")
>>> print("A.size: ", A.size)
A.cols: 24
