I wrote a function which is pretty simple but when I call it gives errors

FUNCTION CODE:

 function [v]=displacement(x,d_1,d_2,phi_1,phi_2,L)
a=[(2/L^3)*(d_1-d_2)+(1/L^2)*(phi_1+phi_2)].*x.^3;
b=[(-3/L^2)*(d_1-d_2)-(1/L)*(2*phi_1+phi_2)].*x.^2;
c=phi_1+d_1;
[v]=a+b+c

MATLAB CODE:

 %DATA
d_1=0,d_2=0,phi_1=0,phi_2=0.0741;L=800;
x=[0:10:800];
v=@displacement([0:10:800];0;0;0;0.0741;800)
fplot(v,x)
xlabel('Position Along Length');
ylabel('Displacement Function');

Answer 1

v = displacement(x, 0, 0, 0, 0.0741, 800) 
 plot(x, v)

I have tried this as well but still following occurs
