size
size of objects
Calling Sequence
y=size(x [,sel]) [nr,nc]=size(x)
Arguments
- x
matrix (including transfer matrix) or list or linear system (
syslin
)- y
1x2
integer vector or integer number- sel
a scalar or a character string
- nr,nc
two integers
Description
- Applied to :
a matrix (constant, polynomial, string, boolean, rational)
x
, with only one lhs argumentsize
returns a1
x2
vector [number of rows, number of columns]. Called with LHS=2, returnsnr,nc
= [number of rows, number of columns].sel
may be used to specify what dimension to get:- 1 or 'r'
to get the number of rows
- 2 or 'c'
to get the number of columns
- '*'
to get the product of rows and column numbers
- Applied to:
a list it returns the number of elements. In this case only
y=size(x)
syntax can be used- Applied to:
a linear system,
y=size(x)
returns iny
the (row) vector [number of outputs, number if inputs] i.e. the dimension of the corresponding transfer matrix. The syntax[nr,nc]=size(x)
is also valid (with(nr,nc)=(y(1),y(2)
). Ifx
is a linear system in state-space form, then[nr,nc,nx]=size(x)
returns in addition the dimensionnx
of theA
matrix ofx
.- Applied to:
an hypermatrix,
y=size(x)
returns the vector of hypermatrix dimensions.[n1,n2,...nn]=size(x)
returns the hypermatrix dimensions.ni=size(x,i)
returns the ith dimension andsize(x,'*')
returns the product of dimensions.
