Shortcut for applying two functions to two arrays.

I know we can apply a function to an array using the feval functionality.

However, is there a way to apply an array of functions to an array of variables?

for example if my first array are the following functions [@exp, @sin] and I want to apply them to [[1 3 5]; [2 4 6]], is there a way to do this in one go? I am looking for something like the feval functionality but for more than one function and one array.

The output of the above example would look like:

[[exp(1) exp(3) exp(5)]; [sin(2) sin(4) sin(6)]]

All the best.

Vectorization ftw!

f = @(x) [exp(x(1,:)); sin(x(2,:))];
vec = [1 3 5; 2 4 6];

out = f(vec)

out = 2×3

Any updates, @Sumer?

Not entierly sure if that's what you want but you can do that

f = @(fun_array,x) [fun_array{1}(x(1,:)); fun_array{2}(x(2,:))];
f({@exp,@sin},[1 3 5;2 4 6])

ans = 2×3
