MATLAB: Error using * Inner matrix dimensions must agree.

error using * inner matrix dimensions must agree.

Hello everyone. Could someone explain why this error is occuring here and correct my code.
I have no idea why dimension problem came out here. I would aprreciate for any conclunsions about it
clc;
clear all;
                    
x1=0:0.001:1;
x2=1:0.001:10;
y=16;
 
a=input('Których chcesz obrać przypadek E<Vo (1) czy E>Vo (2)    ');
if a==1;
disp('Wybrano zalozenie E<Vo');
 
f=1/(1+((1/(4*x1*(1-x1)))*(sinh(sqrt(y*(1-x1)))^2)));
figure (1)
plot(f,x1);
grid on;
title('x1');
elseif a==2;
    disp('Wybrano zalozenie E>Vo');
g=1/(1+((1/(4*x2*(x2-1)))*(sin(sqrt(y*(x2-1)))^2)));
figure (2)
plot(g,x2);
grid on;
title('x2');
end

Unless you meant matrix multiplication, in which case you likely need to transpose one side of the * then what you need is .* for element-wise multiplication.
