Question

I am coding with Matlab, and I get the following error for the bold line (containers = [containers(1:j-1); containers(j+1:end)]😉

Error using vertcat
CAT arguments dimensions are not consistent.

Error in fillContainerWithPolygons (line 77)
                containers = [containers(1:j-1); containers(j+1:end)];

The problem is that I get it just sometimes(not always).

Just in case, containers is a set of the matrix, for example I got error for `containers(1:j-1) = [13×2 double] and containers(j+1:end) =[4×2 double]

I searched and googled a lot but I did not find the problem,
Any idea will be appreciated.

Hmm, you can avoid that by just saying

containers(j, :) = []

Also there’s something off in your question because containers(1:j-1) can’t be 13×2, it’s got to be nx1. I assume you mean containers(1:j-1, :).

I think the reason is that j+1:end is probably just one element, and it’s being treated like a column because you’re not specifying j+1:end, :.
