anonymous-function

Programming

Create an anonymous (lambda) function. The @ symbol followed by parameter list and expression creates a callable function object. Anonymous functions capture workspace variables at creation time.

f = @(args) expression

@(x) x^2

@(x, y) x + y

f = @(x) x^2;
f(5)

g = @(x, y) sqrt(x^2 + y^2);
g(3, 4)

k = 2;
h = @(x) k*x;  % captures k=2
h(10)
