From 777eca813a8030e7a674072c79da144e92dde07a Mon Sep 17 00:00:00 2001 From: Ravi Kumar <119737193+ravi-ivar-7@users.noreply.github.com> Date: Sun, 15 Oct 2023 16:25:56 +0530 Subject: [PATCH] Corrected typo in function name and doctests. rkf45.py (#10518) * Corrected typo in function name and doctests. rkf45.py There was a mistake in name of function (runge_futta_fehlberg instead of runge_kutta_fehlberg) . I have corrected this in function name and also doctest. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Rename rkf45.py to runge_kutta_fehlberg_45.py * Update runge_kutta_fehlberg_45.py --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Christian Clauss --- maths/{rkf45.py => runge_kutta_fehlberg_45.py} | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) rename maths/{rkf45.py => runge_kutta_fehlberg_45.py} (84%) diff --git a/maths/rkf45.py b/maths/runge_kutta_fehlberg_45.py similarity index 84% rename from maths/rkf45.py rename to maths/runge_kutta_fehlberg_45.py index 29fd447b6..8181fe301 100644 --- a/maths/rkf45.py +++ b/maths/runge_kutta_fehlberg_45.py @@ -7,7 +7,7 @@ from collections.abc import Callable import numpy as np -def runge_futta_fehlberg_45( +def runge_kutta_fehlberg_45( func: Callable, x_initial: float, y_initial: float, @@ -33,33 +33,35 @@ def runge_futta_fehlberg_45( # exact value of y[1] is tan(0.2) = 0.2027100937470787 >>> def f(x, y): ... return 1 + y**2 - >>> y = runge_futta_fehlberg_45(f, 0, 0, 0.2, 1) + >>> y = runge_kutta_fehlberg_45(f, 0, 0, 0.2, 1) >>> y[1] 0.2027100937470787 >>> def f(x,y): ... return x - >>> y = runge_futta_fehlberg_45(f, -1, 0, 0.2, 0) + >>> y = runge_kutta_fehlberg_45(f, -1, 0, 0.2, 0) >>> y[1] -0.18000000000000002 - >>> y = runge_futta_fehlberg_45(5, 0, 0, 0.1, 1) + >>> y = runge_kutta_fehlberg_45(5, 0, 0, 0.1, 1) Traceback (most recent call last): ...
