Error: A and B must be floating point scalar? Using Integral function.

Using the integral function I am encountering the error as stated in the title. For the code down below my input is a table of a single column which I convert into an array. To see why this error was occuring within integral, I found that the class type for my second parameter in the integral is 'double'.

This error appears when my input EV is a 494x1 table as I need the integral to go through the first value in the table to the last.

function [y] = Jr_Zero(EV)
    constant = 9.88279.*10.^22;% this is 2pi/h^3 c^2 
    kt = 0.0257 ;
    electron = 1.602.*(10.^(-19));
    data = [] ;
    fun = @(x) (constant.* (x.^2)).*(1./((exp(x/kt)-1)));
    convert1 = table2array(EV);
    for i = convert1
        J = integral(fun,1.9,i);
        data = [data J];
    end 
    y = (0.1.*(2.*electron).*data); % Acm^(-2)
end
