Integral function, input parameter and output as vectors?

Hi!

I know that if I want several different integral values into a vector, I could use this loop:

int = [];

for i = 1:5
   A = integral(@(y) func(y), 0, i);
   int = [int, A];
end

But is it in any way possible to put in a vector instead of making this loop? Something like:

B = 1:5;
A = integral(@(y) func(y), 0, B);

isvector(A) %I want this to be true then.

And thereby get a vector A?

Trying your code with the exp function:

B = 1:5;
A = integral(@exp, 0, B);

it throws the error ‘A and B must be floating-point scalars.’. So the short answer is: No!

However, not knowing what ‘func(y)’ actually is and not being clear on what you want to do, it is possible to integrate array-valued functions if you set the name-value pair 'ArrayValued in integral to true or 1.

For example, you might change your integral call to:

B = 1:5;
A = integral(@(y) exp(B.*y), 0, 1, 'ArrayValued',1);

That syntax works.
