Define matrix function to output matrix

Hello

I want to define sqrt function for matrix with f= fumn(A , sqrt) .

But I can not use this form of definition of matrix function for every function such 1/x or exp(-x) , exp(- sqrt(x)),...

I will be grateful offer your suggestions to me.

thank you

A = rand(3);
fumn(A, @sqrt)

ans = 3×3

0.5456 0.9703 0.9907 0.8551 0.3477 0.4702 0.6054 0.8961 0.8144

fumn(A, @(x) 1 ./ x)

ans = 3×3

3.3599 1.0622 1.0188 1.3676 8.2739 4.5222 2.7286 1.2454 1.5076

fumn(A, @(x) exp(-x))

ans = 3×3

0.7426 0.3901 0.3747 0.4813 0.8862 0.8016 0.6932 0.4480 0.5152

function f = fumn(A, fcn)
f = fcn(A);
end
