I want one of the parameters i pass to odeint to be a function.

In my case, this is the Hubble constant H which should decrease with H ~ 1/t.

This time "t" is exactly the same time that my odeint uses for solving coupled ODEs. (I want to solve equations of motion in an expanding universe and want H to be determined outside of odeint so to speak)

How do i tell odeint that i want H to be decreasing with each time step that odeint is calculating?

The relevant lines from my code are (Here, H is a constant (H=1) but i want it to be H=1/t):

I'm currently working on the last FreeCodeCamp intermediate algorithm and I'm running into a problem pushing multiple objects into an array. I'm passing the first test which is an argument with a single object inside of an array, but I'm failing the second test where I need to return multiple objects from the array arguments passed into it with three objects. I'm only returning the last object in the array

So, basically i have a JSON file

I have pandas data frame and I'd like to extract the values after pb~ and before _ or ' ' or ''. so it's like the string pb~value_ or pb~value' ' or pb~value''.

I have an issue concerning the value of a parameter of an input file in Fortran90 :

the part of input file concerned is :

The current design based on tables looks like this (the pictures are of the different size and ratio; the goal is to make all the imgs and text fit on same line and resize pictures preserving the ratio):

I'm trying to reverse engineer an old sensor interface program (Draeger Pac III). I have meaningful values as reported on the sensor screen and have identified the raw hex data via serial port sniffer. Now I am trying to figure out the pattern to write some code to receive and transmit the data in real numbers on an arduino.

Edit and update: So far this link to another, much newer, Draeger module has been the only possible link available but does not help explain the meaning behind the counting scheme below.

I'm 100% sure these bytes are the bytes of interest. For example this is the raw data from one value from the readout : 01 02 01 05 b0 00 19 00 d2 01 02 01 1d b0 00 00 43 9d 80 00 00 3e cc cc cd 42 5c 00 00 01 01 01 01 02 00 00 04 02 01 01 05 80. The first 8 bytes are the command with a checksum in the 9th position. Up to and including the 21st byte there is no change for each value change and I can only assume these correspond to other status components. 3e cc cc cd some how represents 0.40. 42 5c 00 00 represents 55 (still not sure how). The next section represents on/off for other components and can be changed independently of the two 4 byte data sets representing numbers. The last 2 bytes are the checksum.
