Evaluate an anonymous function for each value in a matrix

I want to evaluate a function for every value in a matrix, but MATLAB thinks I want to input the entire matrix into the function.

f = @(x) x*sin(x);

a = [1 2 3;4 5 6];

f(a)

ERROR: "incorrect dimensions"

^this makes sense because it thinks i want a*sin(a) instead of a(i,j)*sin(a(i,j) for i = 1:3 and j = 1:2

In another implementation like multiplication I would use ".*" to signify elemtwise calculations so I am assuming there is something similar for anonymous functions.

I could use a loop for this example but I want to implement it in a more complicated application so I would be a much larger headache.

Yes, use element-wise operations while defining the function handle

f = @(x) x.*sin(x);
a = [1 2 3;4 5 6];
f(a)

ans = 2×3
