Below are my two scripts of code, one is a function called keplersolve and the other is a script called Test1. When I am trying to run Test1 it won't recall my function keplersolve, I have already ran keplersolve before running Test1, so MATLAB has it in its workspace. If anyone can help me, it'll be much appriciated.

%keplersolve clc clear close all

% E = keplersolve(M,e) function E = keplersolve(M,e) MAXITER = 100; % in case the loop does not converge TOL = 1e-11; % tolerance for convergence En = M; % first guess fn = En - e*sin(En) - M; % f(E) that we want to be zero iter = 1; % count the iterations while ( abs(fn) > TOL ) En = En - fn/(1-e*cos(En)); fn = En - e*sin(En) - M; iter = iter+1; if (iter>=MAXITER) error('Did not converge'); exit end end E = En end

%Test1 clc clear close all

t_T = input('time since periapsis: ') a = input('semi-major axis: ') e = input('orbits eccentricity: ')

T_T = (t_T)*60; % This is a conversion to minutes into seconds

mu = 3.986*10^5;

n = sqrt(mu/(a^3)); % Mean anamoly M = n*(T_T); % Mean motion

keplersolve_(M,e)

Thank you so much, what you told me to do cleared it up.

No it didn't - your code formatting is still messed up. Maybe you were talking about my answer below though.

在 MATLAB Online 中打开

Remove these lines from the beginning of keplersolve:

clc 
clear
close all

It should start with the "function" line. Otherwise that function is privately nested in a script and won't be able to be seen from a separate m-file.
