How to get the measurements with a random walk?
I know that the physical signal has added a random noise, but the measurements are same when I run some times. I simulate the physical measurements, they should be different in practice, How to solve it? I try to change the sigPower in awgn, but it does not work, the measurements are still same.How to get the measurements with a random walk?

Why is Curve fitting tool not giving good results even with the R-square value of 0.99?
I am trying to extract the equation from the matlab example of wind turbine controller design. There is CpData, TSRgrid and Bgrid. But I am unable to get any useful equation from it. At last I used linear curve fitting based on two variables. But results which should be close to 0.48 something are like in -500. It is weird for me. Please do help what I am doing wrong.I am trying to extract the equation from the matlab example of wind turbine controller design. There is CpData, TSRgrid and Bgrid.

FOR Loops for genearting multiple plots and using only one Column of Data from Each Table (Multiple Tables Present)
Hello,
I have a Cell Variable named Complete_Table. Which has multiple Tables within it (3 in the example shown in attached images). I would like to make plots using FOR Loop where in I can Only use the the Third Column of Each Table under Complete Table aganist a Static X-Axis with ("LG","MG","CG") as names No Data in General. In Simple Words the X-Axis doesn’t change so that is not a Issue. In my Loop the Script I have added below I am not able to dynamically index for the Y-Data to Change from First Table (Var1_3) to Second Table (Var2_3) to Third_Table(Var3_3) and So on.
Also The Variable names here are seem same but are different. Like Var1_3 is associated with First Table and Var2_3 is associated with Second table.
for op = 1:length(Complete_table) % Helps us learn the number of tables present in the Cell.
figure;% Produces the Same number of figurs as number of Tables or varable op.
Y_Data = Complete_Data(op()); % here it When op =1 it is looking at the first table but not sure how to proceed for it to look at Var1_3 and so on & so forth.
plot()
end
Any suggestion in the right direction would be great.

Python – MATLAB not working: MATLAB cant find python environment, numpy not working, fooof not working
Hi everyone,
I’ve been stuck on trying to run some matlab-python code for a week now and nothing seems to work. I am trying to run the following code: https://github.com/fooof-tools/fooof_mat?tab=readme-ov-file which requires python to be compatible with MATLAB. I’ve read so many things but nothing has worked so far. This is my first time trying to code in python-matlab simultaneously so the answer might be something simple that I am just not aware of.
What has worked so far:
I created a new environment called ‘env’ which is located in location ‘fri_test’. In this environment I have installed fooof, matlibplot, pandas.
Then, I open a fresh MATLAB window and type in the following:
pyenv
This is the output:
ans =
PythonEnvironment with properties:
Version: "3.9"
Executable: "/Users/c1034944/fri_test/env/bin/python"

Home: "/Users/c1034944/fri_test/env"
Status: NotLoaded
ExecutionMode: InProcess
I then run:
python_env_path = ‘/Users/c1034944/fri_test/env/bin/python’
pyenv("Version",python_env_path);
py.list({‘This’,’is a’,’list’})
output:
ans =
Python list with no properties.
[‘This’, ‘is a’, ‘list’]
Lastly, run this again to check the python environment:
pyenv
output:
ans =
PythonEnvironment with properties:
Version: "3.9"
Executable: "/Users/c1034944/fri_test/env/bin/python"

Home: "/Users/c1034944/fri_test/env"
Status: Loaded
ExecutionMode: InProcess
ProcessID: "42704"
ProcessName: "MATLAB"
As you can see the ‘executable’ is finding the correct location of the environment I created in fri_test. The ‘ExecutionMode’ has also now updated to ‘InProcess’. However, the ‘Library" is still calling the python version from the Library/Developer.
To test if numpy is working, I run the following:
freq=([0 0.9766 1.9531 2.9297])
py.numpy.array(freq)
this is the error message:
Unable to resolve the name py.numpy.array.
More info: The ‘fooof’ code I am trying to run contains the following line: py.numpy.array(freqs), where ‘freqs’ is a list of 1 x 257 numbers. To my understanding py.numpy.array(freqs) converts the matlab (.mat) file ‘freqs’ into a python-compatible array.
Conclusion: I have no idea what is the issue here and why numpy is not working. I know that MATLAB and python versions are compatible, but maybe I am making a different mistake. I am hoping that finding a solution to numpy problem and that may fix the whole issue – is there any other way to convert .mat files into python arrays?
Any suggestions would be helpful!

How to fit this model with a Weibull distribution?
Hi. I’m trying to fit my empirical distribution with a theoretical Weibull distribution.
The problem is that I get a negative value and I can’t understand why.
I tried adding a +c constant to the Weibull function, but it only got worse:
I also tried adjusting the variables’ StartingPoint values but nothing changed.
I am pretty sure this has to work somehow.

How do I estimate and optimize the parameters of my ODE system in MATLAB?
I have a system of ordinary differential equations (ODE) with some unknown parameters (coefficients). I want to simultaneously solve the system of differential equations as well as optimize for the unknown parameters by minimizing an objective function that depends on the solution of the ODE system.

Plotting 1st derivative and 2nd derivative graph from a set of values
I have a set of raw data collected from a displacement time graph and i wish to convert it into a velocity time graph and acceleration time graph. Is there anyway to do that? My data is the time at each interval of displacement so I do not have enough points to plot using the (y1-y2)/(x1-x2) method to extrapolate the gradient. Is there anyway to get the derivatives from the line of best fit? I cannot just differentiate line of best fit polynomial as it becomes a straight line graph after 1.5s so the best method is to find gradient of this graph at many points and plot from there.
