stepper | Stepper is multistep form solution for Rails | Form library

I am new to React and have had some hard time to understand the concept of states.

Down below I export a stepper from MUI. I use state

I'm building a macOS app where I have an observable Formatter object that uses @AppStorage to store the significant digit settings (see Formatter.swift). The number formatter is passed to the other views as an environment object using the main app struct MyApp.swift. In the preferences window SettingsView.swift, the significant digits are adjusted using steppers. Finally, the number formatter is assigned to text fields in ContentView.swift to format the input.

The problem is the text fields in the content view do not automatically update their format when the significant digits are changed in the settings view. The text labels automatically update because they read the app storage values directly. But the text fields are not observing the change to the number formatter. If I change the settings, restart the app, then the text fields will properly show the updated format. But how do I tell the text field to update when the formatter significant digits change?

I'm trying to replicate this stepper like functionality using react.

Below is my stackblitz, How can I achieve this functionality without using any 3rd Party plugins.

I have this stepper attached as an example in fiddle.

I really hope I haven't gone down a dead-end here. I have a Behaviour that gives the currently selected Color, and the current mouse coordinates, then carries out a task when the mouse is clicked. That task involves looking at a list and then updating the values in that list, for it to be retrieved later. The fact that I can "store" the selected color gives me hope that storing a list can be done in a similar manner. I'm just at a dead end and not sure how to solve this. Would really appreciate some help.

I have a stepper inside my application when user selects specific options on first step i want to splice some steps from my step array, but i have splice function on button, so everytime i go back and click button again it splices another item, how can i make it splice only once? here is my array of steps:

I'm getting this error after I've updated the packages in my package JSON file.

I am trying to integrate a very simple ODE using boost odeint. For some cases, the values are the same (or very similar) to Python's scipy odeint function. But for other initial conditions, the values are vastly different.

The function is: d(uhat) / dt = - alpha^2 * kappa^2 * uhat where alpha is 1.0, and kappa is a constant depending on the case (see values below).

I have tried several different ODE solvers from boost, and none seem to work.

Update: The code below is now working.

In the code below, the first case gives nearly identical results, the 2nd case is kind of trivial (but reassuring), and the 3rd case gives erroneous answers in the C++ version.

Here is the C++ version:

I have a list of header icons in a Stepper inside a container and I am trying to get them to be responsive to the page size changes but it is not working. I have tried to change the place of the container in different div but it did not work.

I am using Bootstrap5

Here is the current output:

I am trying to get the numbers inside the container here is the template:
