Output figure as white background in dark mode [2023b beta]
Dear all,
I appreciate for dark mode in 2023b version. However, for the output figure, my output figure works also based on dark mode which means black background and white text color. I take effort to change into "white mode" figure (white background, black text color). I used below code but it just work for one-by-one figure.
set(gca, ‘Color’,’w’, ‘XColor’,’k’, ‘YColor’,’k’)
set(gcf, ‘Color’,’w’)
set(gca,XScale=’log’);
colorPropObjs = findobj(gcf, "-property", "Color");
colorPropObjs(2).Color = [1.0000 1.0000 1.0000];
set(0,’defaultfigurecolor’,[1 1 1]);
I would like to ask there are any ways to work on dark mode but the output figure as normal as white mode. or we can set up output figure at one time.
Thank you for your time,

MCSA spectral analysis using FFT

The sampling frequency was 5000000 Hz, the recording length was 0,2 s and the number of samples was 1000000. Can I ask for help. Thank you very much.Hi,

MATLAB Function always infers outputs as doubles
First, context: I’m attempting to generate HDL code from a Simulink model, which includes a MATLAB Function block. The relevant function is:
function [output, valid] = demux(input)
%#codegen
num_outputs = 24;
% Memory element: demultiplexed outputs
persistent demuxed;
if isempty(demuxed)
demuxed = zeros(num_outputs, 1, ‘like’, input);
end
% Assign from "input" to a single element of "demuxed" here… trimmed for length
% Commit actual values
output = demuxed(1:num_outputs, 1);
In my Simulink model, both input and output are sfix24_En23 types (fixed-point, signed, 24 bits total, 23 bits fractional):
I’ve tried to hint to MATLAB that output should be fixed-point as well, even including this line at the beginning of the function:
output = fi(zeros(num_outputs, 1), true, 24, 23);
This explicitly includes my fixed-point parameters, which isn’t great for maintainability, but would be acceptable for now in order to allow the model to compile.
However, in this and every other case I’ve tested, the Simulink console complains that Inferred type (‘double’) for data ‘output’ does not match back propagated type (’embedded.fi (sfix24_En23)’) from Simulink.

Hello, As part of my master thesis I created a closed loop motor control system with acceleration sensor as input and was in the phase of testing when suddenly i started getting this error below

how to set different axis value?
I want to change the axis display value in a contour plot.
xylim = 0.0055 ;
N = 5; x = linspace(-xylim,xylim,N); y = x;
[X,Y] = meshgrid(x,y);
r = (X.^2 + Y.^2); rho = sqrt(r);
f = 0.011 ;
theta = atan(rho./f) ;
CPhi = X./rho; SPhi = Y./rho;
if mod(N,2) == 1
CPhi((N-1)/2+1,(N-1)/2+1) = 1;
SPhi((N-1)/2+1,(N-1)/2+1) = 0;
end
%% Function
n1 = 1;
n2 = 1.5 ;
thetaI = theta;
Th = theta*180/pi;
thetaT = asin((n1./n2).*sin(thetaI));
CTi = cos(thetaI);
CTt = cos(thetaT);
a = (n2.*CTi – n1.*CTt) ;
b = (n2.*CTi + n1.*CTt) ;
c = (n1.*CTi – n2.*CTt) ;
d = (n1.*CTi + n2.*CTt) ;
Rp = a./b;
Rs = c./d;
figure,contourf(X,Y,Rp,20);
Now the x and y axis has value -5 to +5 mm, from the below image we can see. I want to change the axis value from X and Y to the value of the red cross line of the Th value chart(below image) which is a function of X and Y. So new x axis should be [26.5651 14.0362 0 140362 26.5651} and new y axis [26.5651 14.0362 0 140362 26.5651}. can anyone help me please? Thank you.I want to change the axis display value in a contour plot.

Bayesian Time varying coefficient model
(This is more general econometric question) While I am writing a thesis on how the cyclicality of fiscal policy evolve over time in certain countries using Bayesian time varying regression. There are some questions that I would like to ask.
I know that Bayesian regression requires prior distribution (which is chosen by the model maker) and I have no idea what the prior distribution should be. Should I use non-informative prior?
How does Bayesian time varying regression really works? Is it similar to rolling window method in normal regression or is there a method where I can do time varying coefficient model in Bayesian regression?(This is more general econometric question) While I am writing a thesis on how the cyclicality of fiscal policy evolve over time in certain countries using Bayesian time varying regression.
