An iteration history printer
Project description
IterationPrinter: A simple iteration history printer
When using iterative numerical algorithms it is common
to print after each iteration a message so that a user
can monitor convergence and catch any bugs.
As an example, demo.py implements a simple bisection algorithm
for computing the square root of two.
The following is the output using this library:
Usage
from iterprinter import IterationPrinter
# Initialize the printer by passing formatting information each column
printer = IterationPrinter(it = '4d', obj = '16.6e')
# Print a header for the table
printer.print_header(it = 'iter', obj = 'objective')
# Print a normal line of history
printer.print_iter(it = 0, obj = 5e3 )
# If a particular field is not provided, the column is left empty
printer.print_iter(it = 1)
For a more complete example, see demo.py.
