How to figure out when k means converges for tf idf?

I am fairly new with working with text data. I have a data frame of about 300,000 unique product names and I am trying to use k means to cluster similar names together. I used sklearn's tfidfvectorizer to vectorize the names and convert to a tf-idf…

Triple integral converges to wrong number (TI-84)

I made a program for finding a triple integral of an f(x,y,z) function over a general region, but it's not working for some reason. Here's an excerpt of the program, for when the order of integration is dz dy…

Creating basins of attraction from data file

How can Newton's basin of attraction be created from a data file? I got 10000 points in the range -2, 2 and their zeros for complex function z^3-1. I'd like to plot them with three different colors to create basin of convergence. Data I've…

Break if Newton's method is not convergent

I'm trying to implement Newton's method for polynomials to find zero of function. But I must predict case when function hasn't a root. I'm wondering how can I detect moment when the method becomes divergent and then stop procedure? Thank you in…

Iteration for convergence in Matlab without using a while loop

I have to iterate a process where I have an initial guess for the Mach number (M0). This initial guess will give me another guess for the Mach number by using two equations (Mn). Eventually, i want to iterate this process untill the error between M0…
