MATLAB: An array for multiple LHS assignment cannot be empty

Question

I'm pretty new to MATLAB and I need to use a graphing function inside of another function. Both are user-defined functions.

function 1:

function [ymax,Timpact] = Projectile2(v0,angle,y0)

blah blah finds ymax and Timpact blah blah

blah blah makes t and y vectors blah blah

[] = AnimatedPlot(t,y,0.1);

function 2:

[] = AnimatedPlot(t,y,p);

blah blah graphs as an updating plot that pauses for (p) blah blah

When I run the first function, I receive this error message: An array for multiple LHS assignment cannot be empty.

What should I do to fix this problem and be able to graph my first points using the second function?

Answer 1

Do not use the syntax

[] = SomeFunction()

as a call. If you do not want to return anything, then just leave out the assignment. For example just

AnimatedPlot(t,y,0.1);
