(...) - Stack function
Returns an vector or matrix formed by placing arguments top to bottom.
Arguments are arrays having the same number of columns or they are scalars and column vectors.
In the case of scalar values the stack function returns a column vector containing the list of arguments.
In the next example three column vectors a
, and c
are input as arguments to the stack function.
In order to obtain a matrix the vectors must be in row order. The three row vectors d
, and g
input as arguments to the stack function.
The row vectors can easily be translated to columns in the matrix by applying the matrix transpose to the stack function.
