Question

Here is an example for defining and using anonymous function in Matlab

data = 1:10;            %# A vector of data
f = @(x) x.^2;          %# An anonymous function
squaredData = f(data);  %# Invoke the anonymous function

The anonymous function does have a name f. So why is it called anonymous?

Answer 1

The anonymous function is the expression @(x) x.^2. This expression is a function which is unnamed and hence it’s anonymous. The value f eventually contains the expression though. But the feature itself is usable without a name
