Use newline, comma or semicolon before this statement

I have written a function but keep getting a 'red' error message telling me to 'use a newline, comma or semicolon before this statement'...'this statement' being the addition sign in the first equation. I have tried various alterations but cant seem to get it to work or if I have written it all wrong??

function E = m + (180/pi20)* e * sind(m)* (1 + e *cos(m));
        keeplooping = true;
        while E > 0.005
            E1 = (E - (180/pi20)* ec *sind(E)-m)/(1-ec *cosd(E));
            E1 = E;
            keeplooping;
            if E <= 0.005
                keeplooping = false
                return
            end
        end
    end

I can’t tell if it’s all wrong, but this statement certainly is:

function E = m + (180/pi20)* e * sind(m)* (1 + e *cos(m));

If you want to create a function file, see the documentation on Function Basics (link). If you want to create an anonymous function, see the documentation on Anonymous Functions (link).

I can’t figure out what you’re doing, so I’ll not venture a solution. One possible ‘fix’ would be to delete the function word from this line and just use it as:

E = m + (180/pi20)* e * sind(m)* (1 + e *cos(m));
