Translating matlab to c++ -

-

i`m trying translate matlab code c++ row row without bigger matlab knowledge. went till one:

a = [1; a(:,n)];

i understand matrix generation first row/first column element being 1, im not quite sure next part should do. please give me hint? "a" twodimensional double matrix, "n" loop counter understand.

regards

midin

a(:,n) means: elements (:) column n

so a = [1; elements column n in a]

a = [1; a_n1; a_n2; a_n3 ...]
