% As anonymous function:
f = @(x) integral(@(t) 2 * sqrt(0.0625 - t.^2), -0.25, x - 0.25) / 0.0981747704247;
f(13)

ans = 1.9999e+00 + 1.6526e+03i

% As function:
g(13)

ans = 1.9999e+00 + 1.6526e+03i

function y = g(x)
y = integral(@(t) 2 * sqrt(0.0625 - t.^2), -0.25, x - 0.25) / 0.0981747704247;
end
