function-handle

Programming

Create a handle (reference) to a named function. The @ symbol followed by a function name (no parentheses) creates a callable reference. Pass function handles to functions like ode45, fminsearch, etc.

fh = @functionName

@sin

@cos

@mean

fh = @sin;
fh(pi/2)

sol = ode45(@(t,y) -y, [0, 5], [1])

result = fminsearch(@(x) (x-3)^2, 0)
