size {matlab}R Documentation

MATLAB size function

Description

Provides dimensions of X.

Usage

size(X, dimen)

Arguments

X vector, matrix, or array object
dimen numeric scalar specifies particular dimension

Details

This is an S4 generic function. Vector will be treated as a single row matrix. Stored value is equivalent to dim.

Value

Returns object of class size_t containing the dimensions of input argument X if invoked with a single argument. Returns integer value of specified dimension if invoked with two arguments. If dimen specifies a higher dimension than exists, returns 1 representing the singleton dimension.

Note

Handling of vectors is different than in initial implementation. Initial implementation returned length.

Examples

size(2:9)                       # 1 8
size(matrix(1:8, 2, 4))         # 2 4
size(matrix(1:8, 2, 4), 2)      # 4
size(matrix(1:8, 2, 4), 3)      # 1
