Exam 1 ready to return

• Average = 33, median = 34
• Writing functions in Matlab
  • Function to compute 3x - 2y

            function z = question2( x, y )
                z = 3 * x - 2 * y;
            end

Questions?

What’s a function handle?

• “Function” as call
  • This is how you normally use functions
• “Function” as package of computation that is callable—might be called later, but not now
  • This is what a function handle is
  • Indicated by an @

       sqrt( 16 )
       ans =
            4
       f = @sqrt
       f = 
           @sqrt
       f( 16 )
       ans =
            4
       integral( @sqrt, 0, 4 )
       ans =
           5.3333
       integral( @(x)x.^2, 0, 4 )
       ans =
          21.3333
