st: replicating rows of a matrix

["Lucy Morecroft" <Lucy.Morecroft@trentcancer.nhs.uk>]

Hi Statalist,

I have a 1 x 5 matrix (A) and I am trying to create another matrix B,
which is basically the rows of A replicated k times (so dimensions for B
are k x 5). I am trying to use the nullmat function, which i found
quoted in a message in your archive "st: RE: Filling a matrix", my code
follows:

local k rowsof(C)

matrix A = (1600,6400,7000,7000,7000)

forval i = 1/`k' { 
	mat B = nullmat(B) \ A 
}

Using the above i get an invalid syntax error. Does anyone see what
mistake I am making? Can I use local values with nullmat?

Thanks in advance
