1. Writing functions in MATLAB
Functions are like scripts, only more flexible
Functions are defined by their input and their output
All variables that are declared within a function are erased after the function is executed; only the input and output variables survive
Write the function triple from p. 34 of Matlab for Neuroscientists
Inputs
Function
Outputs
--turn to p. 34 in MfN and work through their simple example of the function 'triple'; extend it by doing 'tripleandquadruple'
--point out that variables used within the function are not available after the function call; this differs from a script
--talk abt. Paths to functions

3. Command window y=triple(x);
Function m-file
function r=triple(n)
r=3*n;
end
Variables in main workspace
Variables in function space x
x copied to n
r is copied to y
r is computed
r and n are destroyed

4. Write a function which computes length of the hypotenuse of a triangle (what are inputs and outputs?)
