Magnitude and phase of the signal using cwt
Hi,
I have a signal in time that I want to analize in the frequency domain using wavelet transform (to balance time and frequency resolution). When I check the magnitude scalogram that is automatically generated using the function cwt, the value of the magnitude that i read is somehow corresponding to the value I am expecting from the time signal. When I try to extract this values computing abs and angle of the coefficients I get from cwt and compare them with expected magnitude and phase, I see there is some scaling factor. I tried to play with the sampling frequency, and it seems to be dependent also on this, but I could not figure out looking into the documentation how to get rid of this scaling factor.
coefs = cwt(signal, scales, wavelet);
mag=abs(coefs);
ph=angle(coefs);
I am taking the magnitude and phase at the freqeuncy where I have the peak, of course, using max(). That’s the one I want to extract.Hi,

Using lookup table with continuous signal
Hi, I’m trying to use LookUpTables with Breakpoints from 0 to 2*pi with input signals that can range from -inf to inf. Since the relationship between the input and output is continuous and repeats, I tried using the MatLab functions WrapTo2Pi() and Unwrap(). Although the LookUpTable combined with WrapTo2Pi() delivers the expected result, I have not found a way to convert the output signal from the table back into a continuous signal without jumps.
I assume that Unwarp() does not work as it only receives one Signal value at a time, and is not able to detect signal jumps because of it. Is there a similar function in Simulink that i could use instead?Hi, I’m trying to use LookUpTables with Breakpoints from 0 to 2*pi with input signals that can range from -inf to inf.

How can I select custom type as parameter type in c-function block?
My main problem is that I want to use a custom device type Q16_t which is declared in a header file q16t.hpp. Because this file inlude several other header files, which also includes headerfile I have a big dependency tree.
In order to trim this problem to an easier starting point, I started with this example:
https://de.mathworks.com/help/simulink/ug/interface-with-c-classes-using-c-function-block.html
I added the source code, include headers and search directories as described in the example, but I am not able to select this class parameter. A picture of all parameter types which I can select is attached.
I tested to import it with Simulink.ImportExternalCTypes but this didn’t have any effect.
I added include header, search directories and source files in C Function block as well as in the model settings simulation target pane to make sure, that files can be found. In model settings simulation target pane the validate custom code is executed without any errors. Did I miss an important setting in advanced parameter menue or anything else?
Any help is appreciated.

Where is the reference ground for the op amplifier in simscape
I want to know what the electrical reference for the op-amplifier is. The output voltage range of a general op-amplifier should be relative to its power supply. But there is actually no defined input power supply for the op-amplifier in Simulink, is the electrical reference the reference ground for the entire system at this time? Will this be a problem in some complex simulation models.
I built a DAB converter that includes an active filter. The op amplifier plays an important role here, but I found that its input end is not dashed.

Image processing for pattern restoration

What optimization/search method is used in wblfit?
I am writing an article about maximum likelihood methods. To understand Matlab methods better, I selected parameters Weibull a=250 and b=1.5 to simulate 50 life tests to failure (no censoring) with rng(1). The parameter estimate results of a=275 and b=1.355 using wblfit were close to the selected values. Contour and surface plots of the loglikelihood values around the parameter values shows a nearly flat surface around values of b = 1.4. What search method is used in wblfit to optimize the results?

Thankyou in advance.Hello All,
I have a shape file from which i have Latitude and Logitude cordinates. In that map when I plot those cordinates using geoplot fuction.
I will put those cordinates here.

So now I looking to create a border around these map on the inside and outside of this boundry. Let say a boundry which is 10 meter apart from the main boundry.
Here is a example of how I want to do it.
If you see in the figure blue line is the actual boundry and red and black boundry is that I am trying to find a function for it.
Is there a way to do it ? I have tried similar methods but those where on the images which can reduce size but not sure how to do it in actual map.

memory section ‘code_ramfuncs’ error with f28379d
Hi!
I am trying to execute a block in the RAM but I cannot find that option in the block parameters of the subsystem:
I followed the steps specified here and the tic2000demospkg package appears.
What should be done to be able to have all the memory sections from tic2000demospkg? Is it neccesary to "load" that package somehow?
Thank youHi!

Bug in PCB antenna designer ?
Hello, I’m having a trouble with pcb designer, for example here I’m trying to set Ly as the length shown in the properties of y, which I’ve done with many others, any tip ? Also I have trouble trouble saving my sessions, if I save it sometimes there will be no save at all and I’ll lost my previous work. Thank you for help, Mathias Bedossa.Hello, I’m having a trouble with pcb designer, for example here I’m trying to set Ly as the length shown in the properties of y, which I’ve done with many others, any tip ?
