How to do this flowchart?

I am having some trouble with the while loop here. It seems like the sorting of my code is not working. I am locating the sorting algorithm outside the while loop.

What sorting are you referring to?

[Ygor Marca]

I am reading the capacitor's voltage and doing a sorting to connect the capacitors with lower or higher voltage.

For example:

[B, Ia] = sort(Uc,'ascend'); %Lower voltage submodules

Which: Uc is the capacitor's voltage

[Walter Roberson]

It looks to me as if you should be using min() and max() instead of sort() ?

[Ygor Marca]

Because I need all the capacitor voltages

[Walter Roberson]

No, the flowchart requires connecting or bypassing the highest or lowest among the voltages. That does not require sorting, just min() or max()
