Hello,

I have been the following code to calculate an integral:

Price = @(z, pg0, pf0, epsilon) ...

(pg0.^(1-z) + pf0 .^(1-z)).^(1./(1-z)).^(1-epsilon); %

AvgPrice = integral(@(z) Price(z, pg0, pf0, epsilon), 0 ,20) ;

where pg0, pf0, epsilon are scalars. Is there a way to do this when the inputs are in a matrix, for instance when each input is a 5 by 1 matrix, to calculate the integral by using inputs from each row? So the output (AvgPrice) will also be a colum vector (5 by 1) with each element being the value of the integral? I can use a loop and run it five times but I wonder if there's a more efficient way to do it.

Thanks very much for your time!
