B must have 2 columns. The Join Tables task lets you interactively combine two tables by performing joins or by concatenating the tables horizontally or vertically. You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. Accepted Answer: the cyclist. Theme. sites are not optimized for visits from your location. Examples expand all Join Tables Using Live Editor Task Parameters No conversion needed. Reload the page to see its updated state. On the other hand, if what you really want is, "vertcat the two tables but only keep one copy of common rows", then perhaps outerjoin is what you want. Thanks once again for helping me to better understand matlab. input along the first dimension. I have two large tables I want to combine. When I try to combine th.
