Oh god! This is so complicated( my function is a squared bessel function)! I will try it though.thank you so much!

for example, for correlation... The correlation of a function with itself is called its autocorrelation In this case the correlation theorem becomes the transform pair – This is the Wiener-Khinchin Theorem Corr(g,g)↔G( f )G*( f ) = G( f )^2 Is there something like that for convolution?

Hallo there! I was wondering wether there is an easy way to convolve a function with itself. For example is ther an easy formula or something that gives directly the result? thanks in advance

:):):) thank you!

Hallo there. I m trying to integrate a bessel function but with no great success... I thing it can't be calculated.. I m trying to simulate the airy pattern of a certain aperture radius and wavelength in matlab. the integral is : int (besselj(1,16981.9*sin(x)))^2/ sin(x) dx where you can...
