but my assignment is:

" Define a function named projectile_position that computes and returns [x,y] where x is the distance a projectile has traveled along the ground from its position at time 0 seconds and y is the height of the projectile in meters. Your function must compute these values based on the initial conditions at release and the current time in seconds (t). This function must also work for vectors of time values. "

this is what my .m file looks like

========================================================

function [x, y] = projectile_position( vi, h, time, angle )

%

% vi = initial velocity of projectile

% h = initial height of projectile

% time = time it takes projectile to cease motion after it's trajectory

% angle = angle at which projectile is launched

%

x = vi*cos(angle)*time;

y = h + vi*time*sin(angle) + 0.5*9.81*time^2;

========================================================

problem is when i input some values after defining this function, for example:

projectile_position( 20, 5, 10, 30)

it only returns one value, but i need it to return 2!! any help is greatly appreciated.
