Hi all. I am trying to use the Error (misclassification probability or MSE) function. In the help documentation it shows an example of useage as err = error(B,TBLnew,Ynew). I tried this with err=error(Mdl,Inps,Outs) with Mdl being the LSBOOST ensemble, Inps being the matrix of vars and Outs being the target. If I try this I get ‘Error using error Too many output arguments.’ . I presume I’m missing something here but can’t seem to find a an example.Hi all.

Hello,
I was trying to create a simple function on matlab, I already have a file named "AddOne.m", so it should work, however at the first line of code, matlab throws the following error
"Error: Function definition not supported in this context. Create functions in code file.". Any ideas how to sort this out?
Thanks in advance!Hello,

I have two figures, which I want to put side by side in my thesis.
These two figures have different x and y labels and ticks, therefore, generally their horizontal axes are not on the same height.
That is ugly.

Good evening!
I am trying to create a set of FIR filters (using designfilt) to apply to some audio signals, and I’m having an issue.
When I try to use a ‘bandstopfir’, for some reason the whole signal is amplified around +320dB (while ‘bandpassfir’, ‘lowpassfir’ and ‘highpassfir’ are working correctly)
Here’s a quick example of the code I’m using, and I added the resulting images of each of these cases showing the issue:

clear

filterObject1 = designfilt(‘bandstopfir’,’FilterOrder’,301,…
‘CutoffFrequency1′,2000,’CutoffFrequency2′,4000,’SampleRate’,48000);

filterObject2 = designfilt(‘bandpassfir’,’FilterOrder’,301,…
‘CutoffFrequency1′,2000,’CutoffFrequency2′,4000,’SampleRate’,48000);

Here are images using fvtool to show both filter responses:
Bandstop (incorrect behaviour):

Bandpass (expected behaviour):

Is this a bug, is the installation I’m using somehow broken, or am I doing something wrong?Good evening!

Hope you all well, i have GUI app which is getting data from national instrument and give back live plot after trun switch on and when switch is off the recorded data wil stop and real time data will stop, however i am trying to intesert another button to clear the previous or delete them from store array however it won’t happened i tried clear func and clf to remove plot and delete the array nothing working i will place the code blow and screen shot of the app design if you could help me to solve this i would be supre greatfull to you what i want is that the previouse data from block 1 and 2 get deleted after clear data button is clicked

end Hope you all well, i have GUI app which is getting data from national instrument and give back live plot after trun switch on and when switch is off the recorded data wil stop and real time data will stop, however i am trying to intesert another button to clear the previous or delete them from store array however it won’t happened i tried clear func and clf to remove plot and delete the array nothing working i will place the code blow and screen shot of the app design if you could help me to solve this i would be supre greatfull to you what i want is that the previouse data from block 1 and 2 get deleted after clear data button is clicked

It doesn’t always happen but I’d like to know if anyone has an idea why this might be happening and if it affects the training or not. Warning: 1 worker(s) crashed while executing code in the current parallel pool. MATLAB may attempt to run the code again on the remaining workers of the pool, unless an spmd block has run. View the crash dump files to determine what caused the workers to crash.
As I have the home licenses I’m not sure what to do with the error above. The script is training a Trebagger model with parallel turned on. It does use a lot of memory but still fits within the 32GB I have. The log is :-

Hello, I am attempting to generate a graph of the full width half max (FWHM) of multiple sets of data but want to first fit each dataset to a Gaussian. Currently, I am calculating the FWHM by indexing the first and last instances of the half-max value for each dataset, then graphing all of these values. This works alright; however, I would like to improve upon this by fitting each dataset to a Gaussian distribution and then use the calculated Gaussian coefficients from the fitting in order to find the FWHM, as this would be more accurate. I have been able to fit each dataset to a Gaussian using the fit() function. However, I have run into an issue where I seem to be unable to access the generated Gaussian coefficients, which are what I need in order to be able to recalculate the FWHM. Does anyone know how I might be able to access these coefficients or generate them in such a way that I would be able to access them? Below I have copied the portion of my code where I am fitting the data along with a screenshot of the particular math I am referring to using the Gaussian coefficients to calculate the FWHM. Thank you so much!
y_fit = data.’; % turns data into a variable for fit, transposes to column
l_y = length(y_fit); % generates a variable with the length of y_fit
x_fit = linspace(0,l_y,l_y).’; % creates a column variable simply for the x-axis
data_fit = fit(x_fit,y_fit,’gauss1′); % this creates a fitted data setHello, I am attempting to generate a graph of the full width half max (FWHM) of multiple sets of data but want to first fit each dataset to a Gaussian.
