My B matrix which represents the coordinates in the Y axis is as follow: also the same numbers for every layer (in the Z dimension). It is indeed very well supported software. So you have to figure out how X,Y and Z should be combined to yield your D, like, for example, 2. . It was a mistake on my part, the matrix must have the dimensions 26x300. And after that i combine all b matrices to C matrix (x3). https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#comment_734509, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#comment_734513, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#answer_387384, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#comment_735652, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#answer_387375, https://www.mathworks.com/matlabcentral/answers/475947-combine-three-matrices-every-other-column#answer_387380. https://www.mathworks.com/matlabcentral/answers/248344-combine-3-matrices-3d, https://www.mathworks.com/matlabcentral/answers/248344-combine-3-matrices-3d#answer_195799, https://www.mathworks.com/matlabcentral/answers/248344-combine-3-matrices-3d#comment_315958, https://www.mathworks.com/matlabcentral/answers/248344-combine-3-matrices-3d#comment_315983, https://www.mathworks.com/matlabcentral/answers/248344-combine-3-matrices-3d#comment_316160.
