I'm modifying some code that generates 2D barcodes to provide "zoom" functionality.
Each barcode is represented by a matrix (list of lists) in Python.
Zoom is provided by repeating each matrix element and row by a number of times equal to an integer…

How can I reduce the stress score from a Multidimensional Scaling (MDS) analysis?
I have a precomputed distance matrix that I have run through Sklearn's MDS algorithm. All data are needed. The matrix has been scaled (0-1). I am looking to convert the analysis into a plot so the max n_components = 3.
I've tried to modify…

Scaling of parameters for a large order of magnitude 1e-26 to 1e-15?
I have parameters and they range in different order of magnitude.
T1 = 1e-26;
T2 = 1e-19;
T3 = 1e-18;
T4 = 1e-17;
T5 = 1e-16;
They are calculated at some conditions e.g temperature.
The scaling should be done in a way that the
values…

What is a memory efficient way to resize a large 3D array?
I have data from a sensor that addresses each event for each (x,y) coordinate pair for each given timestamp.
An example of the data from the sensor would be something like:
timestamp = [ 1, 1, 2, 3]
x = [ 25, 25, 60, 30]
y = [128, 120, 50, 50]
