Nested integral within integral2 in matlab -


i'm attempting take double integral (using integral2) of function defined integral.

here attempting:

t=linspace(0,1,50); fun_1= @(v) exp(.071*v) fun  = @(x,y) exp(0.14*0.00607*integral(@(u)fun_1(u),0,x)).*exp(-(x-y).^2).*exp(0.14*0.00607*integral(@(u)fun_1(u),0,x)); i=2:length(t)     j=i:length(t)     a(i,j)=integral2(fun,t(i-1),t(i),t(j-1),t(j));     end end 

i'm receiving error

error using integral (line 86) , b must floating point scalars.

can provide information on how fix problem.

here go:

l=3; t=linspace(0,1,365); fun3= @(v) integral(@(v)exp(.071*v),0,v,'arrayvalued',true); i=2:length(t)   j=i:length(t)       xx=t(i);       yy=t(j);       fun  = @(x,y) exp(0.14*0.00607*fun3(yy)).*exp(-(x-y).^2/l).*exp(0.14*0.00607*fun3(xx));       y(i,j)=integral2(fun,t(i-1),t(i),t(j-1),t(j));   end end 

it works, slow.
