I keep the Round shape for when I want to make it obvious that there is a feedback involved: There is no absolute rule, but personally I like to use the Rectangular shape when implementing equations that flow from left to right, without obvious feedback. The SOS programs can be solved using SeDuMi, SDPT3, CSDP, SDPNAL, SDPNAL+, CDCS and SDPA. SOSTOOLS can be used to specify and solve sum of squares polynomial problems using a very simple, flexible, and intuitive high-level notation.

One question remains: When should the Sum block be Round and when should it be Rectangular? SOSTOOLS is a free MATLAB toolbox for formulating and solving sums of squares (SOS) optimization programs. One way I like to use the Sum block is to sum all the elements of a vector or matrix:ДЇor matrices, the Sum block can also be configured to Sum only over one specific dimension: So I almost always remove the '|' when I change the shape to Rectangular.

Personally, I can not think of a good reason for skipping a port in Rectangular shape. If you change the Icon Shape property of the default Sum block to Rectangular, the block will look like the following: For example, if we want to add a port on top of the block, we can modify the list of signs: When the Sum block Icon Shape is set to Round, the ports are spread evenly from top to bottom and the vertical bar '|' can be used to skip one position. When you drag the Sum block from the Simulink Library Browser, its Icon Shape is set to Round, and it has one input port on the left and one on the bottom: Here are a few tips to format the Sum block to make your models easier to understand. I have realized that many users do not know how to, or do not take the time to configure the ports of the Sum block.ДЇor example, when I see things like this, it makes my eyes hurt a little:

Working in technical support, I see a lot of Simulink models from users.
