How to solve the error of solving bessel function

I want to solve Bessel funnction using for loop, but it always give me the warning: Undefined function 'slove' for input arguments of type 'sym'.

Here is my codes:

clc; clear all; close all;

syms a

n2 = 1:0.001:1.44;

n1 = 1.445;

y = n2/n1;

d = y.^2+1;

for n3 = 1000:1440

a1 = (((n3*0.001)./n1).^2+1)*besselj(1,a);

b1 = (a*besselj(2,a));

c1= a1-b1==0;

e= slove(c1,a);

end

plot(e,y,'b')

You have a typo in your code. You want to call the solve function, not the slove function.
