Exchange Server 2019 Installation Fails with too many prerequisites check errors!
Hi Brain Trust,
I’m trying to install Exchange 2019 server to replace my current Exchange 2013 server. I have all required permissions (Schema Admin, Enterprise Admin, Organization Management etc etc..) in the current environment and the Domain, Forest Functional levels are 2012 R2 as well. When I’m trying to run the exchange setup, the prerequisite check fails with a load of errors!
Our AD environment is very simple. Single domain with about 6 DCs.
Does anyone have an idea what could be causing this?

When using ‘quadprog’ how do I limit certain solutions so that they can only become whole numbers?
As stated above, I am trying to minimize a quadratic function where some of the solutions have to be whole numbers for the function to work.
I have done a similar problem to this one but with a linear function, however in that case I only had to set the desired solutions as integers and then use ‘intlinprog’. Unfortunately there is no such option (to my knowledge) for ‘quadprog’ so I’m interested to know if someone has a possible workaround.

File Replacement:
Another trigger for the QBDBMgrN error is when your company file gets replaced by another file with the same name in the directory. This file replacement can cause conflicts that affect the proper functioning of QBDBMgrN on your computer.
By addressing these triggers promptly and implementing the necessary solutions, you can effectively resolve the “QBDBMgrN Not Running on this Computer” error. Remember, accurate troubleshooting is key to ensuring seamless operation of QuickBooks and preventing disruptions in multiuser mode services and data accessibility.

Removing empty cells from cell array with multiple rows while preserving the rows
I have cell array of string values with empty cells in some of in the middle of some of the rows. I would like to delete the empty cells and shift the cells to the left but I don’t want any shifting to happen in between rows. I tried the code below but it returns cell array of cell arrays. How can I modified the code so it returns a cell array of string values like the orginal array but only the empty cells removed?
compacted_instances = {};
for i = 1:size(instance_array_nolateral, 1)
% Get the current row
current_row = instance_array_nolateral(i,:);
current_row = {current_row};
% Remove empty cells from the current row
compacted_row = current_row(~cellfun(‘isempty’, current_row));

Selecting appropriate values for the parameters in the Gierer-Meinhardt activator-inhibitor model
For the following activator-inhibitor system (Alfred Gierer-Hans Meinhardt model),
with all constants positive and initial conditions , examine the effect of the parameters () on the behavior of concentrations . Initially, we have to consider .
My problem is that I don’t undestand how to choose the right parameters every time. For example but the code works and for or but when I chose you can see below, the results are not correct.
Could anyone explain please? Thanks in advance
