I'm new in matlab and I'm stuck with this error for sometime, if someone could help
function [thetadotdot] = acceleration(r,g,a_c,theta,k0)
thetadotdot = ((g.*r.*sin(theta))+(a_c.*r.*cos(theta)))./k0^2;
end
clc;
clear;
theta = 0.25*pi; % 45 degrees in radians
g = 9.81; % acceleration due to gravity
m = 40; % mass in kilograms
r = 0.4; % radius in metres
k0 = 0.5; % radius of gyration in metres
a_c = 10*g; % deceleration in N/m2
thetadot = integral(@(thetadot) acceleration(r,g,a_c,theta,k0),0,45,'ArrayValued',true);
Error in Acceleration (line 9)
thetadot = integral(@(thetadot) acceleration(r,g,a_c,theta,k0),0,45,'ArrayValued',true);

I didn't get any error. Can you paste the complete error message?

Cannot find an exact (case-sensitive) match for 'acceleration'
The closest match is: Acceleration in C:\Users\RSula\OneDrive\Documents\MATLAB\Acceleration.m
Error in Untitled5>@(thetadot)acceleration(r,g,a_c,theta,k0)
Error in integralCalc/iterateArrayValued (line 156)
fxj = FUN(t(1)).*w(1);
Error in integralCalc/vadapt (line 130)
[q,errbnd] = iterateArrayValued(u,tinterval,pathlen);
Error in integralCalc (line 75)
[q,errbnd] = vadapt(@AtoBInvTransform,interval);
Error in integral (line 88)
Q = integralCalc(fun,a,b,opstruct);
Error in Acceleration (line 9)
thetadot = integral(@(thetadot) acceleration(r,g,a_c,theta,k0),0,45,'ArrayValued',true);
^^^this the whole error
