I have own function wrote. I used an algorithm, which was written in Matlab. in matlab: ... gamma = inv(v)*g; ... #v = matrix of variable size, v=vv(k) => k=2 => dimension of v 2x2 #g = a line vector with 4 elements e.g. g=[1,0,2,0]; my rewritten r-file: ... gamma = solve(v)*g; ... which is my error? Who can help me? thank you in advance. Chris

Ehhh, don't know what Matlab does with the code given above. In R: If v is 2x2 and g has length 4, this seems to be strange, but the matrix is treated as a vector for the multiplication step and there should not be an error message (but probably not the result you want to get) ... Uwe Ligges
thank you in advance. Chris
A quick reply, are you looking for the matrix multiplication operator? In R it's %*% Henrik

... and solve(v,g) is probably preferable anyway.
