Description

|
•
|
The functions rowdim(A) and coldim(A) return an integer, the number of rows and columns respectively, in the matrix A.
|
|
These functions are part of the linalg package, and so can be used in the form rowdim(..) only after performing the command with(linalg) or with(linalg,rowdim). These functions can always be accessed in the long form linalg[rowdim](..).
