tformarray matlab function equivalent in opencv

tmap_B = cat(3,u,v);

resamp = makeresampler('linear','fill');
J2 = tformarray(I,[],resamp,[2 1],[1 2],[],tmap_B,.3);

I want to port the above matlab code to corresponding opencv, where u and v are two 2D matrices. The cat() function corresponds to the concatenate procedure, from a short research I came up with the hconcat() and vconcat() but these are for horizontal and vertical concatenation respectively. Is merge() what I should use instead or there is something else?

As for the tformarray() corresponds to a spatial transformation to an array A in order to produce an array B. I am trying to figure out which is the equivalent from the opencv transformation functions. Any idea?

ok the following code is the equivalent in opencv:

std::vector<cv::Mat> channels;

channels.push_back(u);
channels.push_back(v);

Mat tmap_B;
merge(channels, tmap_B);
Mat output;
remap(I, output, tmap_B, Mat(), CV_INTER_LINEAR, BORDER_CONSTANT);

I guess is quite late, and apparently I need some sleep :-p....
