I want to use the integral function in Matlab 2012a to integrate the function
phi = @(x) integral(@(t) exp(-t.^2./2),-inf,x);
but I get an error when the integrate function passes vector-valued x to
integral(@(t) exp(-t.^2./2),-inf,x);
I tried to define a function
function out = innerIntegralMultiple(x)
inner = @(t) exp(-t.^2./2);
if(isscalar(x))
out = integral(inner,-inf,x);
return;
end
out = zeros(length(x),1);
for i=1:length(x)
out = integral(inner,-inf,x(i));
end
end
and define phi as
phi = @(x) innerIntegralMultiple(x)
but I get errors about the number of arguments the function returns when I try this definition.
Is there a way to do what I want?
