MTM

 size
 size of an array in each dimension Calling Sequence size(M) size(M, n) Parameters

 M - array n - positive integer dimension Description

 • The size(M) function returns an array with the number of rows as the first entry, and the number of columns as the second entry.
 • When M is a row-vector, the result of size(M) will have a 1 in the entry specifying the number of rows.  Similarly when M is a column-vector, there will be a 1 in the second entry of the result.
 • When M has more than 2 dimensions, the number of entries in M will correspond to the number of dimensions of M.
 • When n is given, size(M,n) will return only the number corresponding to that dimension.  size(M,1) will give the number of rows and size(M,2) will give the number of columns.
 • When n is larger than the number of dimensions of M, 1 will be returned. Examples

 > $\mathrm{with}\left(\mathrm{MTM}\right):$
 > $\mathrm{size}\left(\mathrm{Matrix}\left(2,3\right)\right)$
 $\left[\begin{array}{cc}{2}& {3}\end{array}\right]$ (1)
 > $\mathrm{size}\left(\mathrm{Matrix}\left(2,3\right),2\right)$
 ${3}$ (2)
