[John D'Errico]

Please stop asking the same question repeatedly. This is now the third time I have seen essentially this same question, and the second ime you have asked identically the same question.

Answer 1

[Steven Lord]

Parameterize the function you pass into the integral function. See the "Parameterized Function" example on the integral documentation page for a concrete example.

Answer 2

[Torsten]

integrand = @(f,y)y.*sin(f(y));
F_alpha = @(f,alpha,x)alpha.*x.*integral(@(y)integrand(f,y),0,1);
f = @(u)u.^2;
alpha = 1;
x = 2;
F_alpha(f,alpha,x)

ans = 0.4597
