Why isn’t this breaking the loop?
I have tried to use an ouptut argument to make a variable and use that variable in my main script, however when it is returning the value I want, it still isnt breaking the while loop?
Code for the function:
function continueChoice = cont()
continueChoice = listdlg("SelectionMode", "single", "ListString", ["Continue", "Exit"], "PromptString", "Would you like another statistic?")
end
Code in the main script:
data = readtable(‘alltimeteams.xlsx’,’VariableNamingRule’,’preserve’);
x = 0
while le(x,210)
x = x+1
choice=listdlg(‘SelectionMode’,’single’, ‘ListString’,data.Franchise,’PromptString’,’Please choose a franchise’); % all possible franchises
if isempty(choice)
fprintf("Please choose a franchise next time n")
break; % Exit the loop if no franchise is chosen
end
% the following is the problematic part
Wpercentchoice = listdlg("SelectionMode","single","PromptString","Would you like the win%?","ListString",["Yes","No"]);
if Wpercentchoice == 1
WinPercentcalc(data,choice); % calculates the overall win percentage (seperate function)
cont()
end
if isempty(continueChoice)
fprintf("Thank you!") % exit the loop if another statistic is not wanted
break;
elseif continueChoice == 2
fprintf("Thank you!") % exit the loop if another statistic is not wanted
break;
end
This is what shows in the command window after selecting "exit" in the listdlg
continueChoice =
2
ans =
2
continueChoice is 2, so shouldnt it work? It just carries on with the rest of my code instead.
Please lmk if any more info is needed.
P.S the reason I’ve made a function which is so short is because one of the criteria for the project im doing is that it has to have a function which has an ouptut argument and this is the only thing I could make one for , I understand it’d be a lot easier just doing it in the main script.I have tried to use an ouptut argument to make a variable and use that variable in my main script, however when it is returning the value I want, it still isnt breaking the while loop?

effects of ifft2(x, ‘symmetric’) while x is not conjugate symmetric
Hi all,
I understand that ‘symmetric’ in ifft2 assumes data is conjugate symmetric and will output real values, but I want to know how exactly is this done. Specifically:
with ‘symmetric’, will only half of the data be used or still the whole matrix is used, but just output real values?
if x is not conjugate symmetric but I still pass in ‘symmetric’, what will happen?
Thanks in advance.Hi all,

How to find rates of return to baseline after peaks, in temperature data over long timecourse?
Hello all, new MatLab user here, find the tutorials and documentation very useful so far! I am trying to evaluate the performance of a freezer in my lab. I wish to know the rate at which it cools back down to its setpoint after a spike in temperature. I want to be able to determine these rates for events over two years
I’ve been able to import the data into matlab as a table with the datetime and temperature, and then use the "find local extrema" task to identify the peaks. But I am now stuck on how I can find the rates of change after these peaks in an automated fashion. I also converted the data into timetables and tried doing this in the Signal Analyzer app. Would anyone be able to point me in the right direction?

Is There a Way to Create a Sequence of Polar Plots in a Tiled Layout Using arrayfun with an Anonymous Function?
Sample data
s.th = pi/4:pi/4:2*pi;
s.r = [19 6 12 18 16 11 15 15];
s(2) = s(1); s(2).th = s(2).th*1.3;
If I want to make two plots in a tiled layout with Axes I can do this
figure
t = tiledlayout(1,2);
arrayfun(@(s) scatter(nexttile,s.th,s.r),s)
However, if I want to make polar scatter plots
figure
t = tiledlayout(1,2);
try
arrayfun(@(s) polarscatter(nexttile,s.th,s.r),s)
catch ME
ME.message
end
Right. nextile does not return a PolarAxes object.
But there doesn’t seem to be a way to force nexttile to create a PolarAxes nor can I find a function like a hypothetical nextpolar to use as the first argument to polarscatter.
Instead, as best I can tell a loop is required
figure
t = tiledlayout(1,2);
for ii = 1:2
h1 = nexttile;
polarscatter(s(ii).th,s(ii).r)
end
What’s interesting here is that nexttile creates an Axes and then deep in the bowels of polarscatter a PolarAxes is created based on some properties of that Axes, and then Axes is deleted

The single function is not behaving as expected
I’m trying to use single to save disk space because my files are very large. I know it could affect the precision if my numbers have many places after the decimal point. However, it is altering my integers as well.

ans =
340580096.00

I am unable to make the new vesion of spectrumAnalyzer show distortion measurements.
I have a Matlab script that has worked fine in R2021b and earlier which I still use today. It simply reads my audio on a Macbook Pro running MacOS 12 and presents a spectrum on the analyzer. Moving that script to the new R2025b and modifying the script to call the new spectrum analyzer seems to work to present the spectrum but when I select "Measurements" and "Distortion" the distortion data appears but does not seem to find the main tone and in-turn the harmonics. I am stuck using the old version of Matlab since that works. I think I may be missing a configuration command on the new analyzer that wasn’t required on the old one. The tone below is on CH1 and CH2 identically. CH2 appears in front of CH1.I have a Matlab script that has worked fine in R2021b and earlier which I still use today.

Generate Graph Nodes and add buttondown callbacks for interactivity
I’m trying to create a graph that brings up a dialogue box when one of the nodes is clicked. I use
NodeTable = table(‘Size’,[0 4],’VariableTypes’,{‘double’,’string’,’double’,’double’}, …
‘VariableNames’,{‘Code’,’Name’,’Latitude’,’Longitude’});
EdgeTable = table(‘Size’,[0 2],’VariableTypes’,{‘cell’, ‘double’}, …
‘VariableNames’,{‘EndNodes’,’Distance’});
nodetemp = inputdlg(["Node Name", "Latitude", "Longitude"], "Node Details");
%check input present
if isempty(nodetemp)== 0
%check node not present in table
if any(matches(app.NodeTable.Name,nodetemp(1),IgnoreCase=true))==false
%format table and add code in column 1
nodeinp = addvars(cell2table(transpose(nodetemp),’VariableNames’,{‘Name’,’Latitude’,’Longitude’}), app.index, ‘before’, 1,’NewVariableNames’,{‘Code’});
%update graph with node data
app.NodeTable=[app.NodeTable; nodeinp];
app.G=addnode(app.G,nodeinp);
app.map = plot(app.UIAxes,app.G,’NodeLabel’,app.G.Nodes.Name,’EdgeLabel’,app.G.Edges.Distance);%plot graph
%set node coordinates
app.map.XData = str2double(app.NodeTable.Longitude);
app.map.YData = str2double(app.NodeTable.Latitude);
app.index = app.index + 1; %increment node counter
end
end
to create the graph, add nodes and plot it. I then am attempting to use
nodes=findobj(app.map,’Marker’,’o’);
nodesLength = length(nodes);
for count=1:nodesLength
nodes(count).ButtonDownFcn=@(src,event)nodeButtonDown(app,count);
end
to get a hold of the node graphical objects and assign callbacks as advised here but the plot doesn’t seem to generate the nodes as children/separate objects like it says in all the documentation.

Add Tooltip to each UI Tree Checkbox in App Designer
In App Desinger I want to add tooltips to each ui tree checkbox, so here each checkbox shall tell the user more of what is done or checked with the check exactly. Example: For "Block Colors" a tooltip might show something like "Checks if each Simulink Block has its dedicated color as defined by the company guidelines". Is there an option, as I can only find to add a tooltip to the parent CheckBoxTree but not each individual checkbox?
