Hi
I want to solve the integral of (delta/A^2) between 0 and 0.9999999.
delta and A^2 are double workspace variables I have saved as txt files.
My Script so far for this is
load ASqr.txt
load delta.txt
realZeros = (1/pi).*(int('delta./ASqr',0,0.9999999))
format long e
realZeros
When I run the script in the command window the following error is being thrown up
Undefined function 'int' for input arguments of type 'double'
Which I am unsure about, would anyone be able to guide me on where I am going wrong, as solving integrals in matlab is new to me. Thank you in advanced.

I'm not sure wha't is the function you want to take the inetgral from. I guess it's Dirac or as you said delta, if you want to perform a symbolic inegral you have to define a symbol first
syms x
y=int(dirac(x))
subs(y,.999)-subs(y,0)
Which gives you 1 anyway! Hope that wouls solve the problem! Good luck!
