MATLAB size function
Provides dimensions of X.
size(X, dimen)
X |
vector, matrix, or array object |
dimen |
numeric scalar specifies particular dimension |
This is an S4 generic function.
Vector will be treated as a single row matrix.
Stored value is equivalent to dim.
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.
Handling of vectors is different than in initial implementation.
Initial implementation returned length.
