matlab error message

I am writing a program for calculating equations of motion . i keep getting this error message

??? function[s n]=eqm1ct(o,~)
    |
Error: Function definitions are not permitted in this context.

function[s]=eqm1ct
x=0;
if (x == 1)
    w = 1;
    while w > 0
        u = inputdlg('Enter the Initial velocity:');
        [o w]=errchck1(u);
    end
    if (o ~= 5)
        w = 1;
        while w > 0
            a = inputdlg('Enter the Acceleration:');
            [o w]=errchck1(a);
        end
    end
    if (o ~= 5)
        w = 1;
        while w > 0
            t = inputdlg('Enter the Time:');
            [o w ]=errchck1(t);
        end
    end
    if (o ~= 5)
        u = str2double(u{1});
        a = str2double(a{1});
        t = str2double(t{1});
        vf = (u+(a*t));
        uiwait(msgbox(['The Final velocity is: ',num2str(vf)]));
        s = 'finalvel';
        savefilec(s, vf)
    end

thats a apart of the function

Please apply a poper code formatting as explained in the "Markup help" link.

Function can be defined in function files and as nested functions insider another function, but not inside a script or in the command window.

My guess is that you are either trying to define a function at the command prompt or in a script. Functions are only allowed to be defined in an m file, which only has other functions (i.e., no scripts). See:
