Hi
Please help me do the following math operation and apply every array of a vector (x) on it,in matlab:

x=randn(1,1000);

diff(log(quad(@(w)exp(jxw-abs(w)^2,-500,500))) {I use quad because the function is not closed formula)

in the other words i want to integral from this function [jxw-abs(w)^2]dw

The phrase is derived in terms of X,

after that put logarithm on it(Ln),

next differentiation with respect to x,

then placed array of vector x individually to the result,

Apologies for the language...

best regards
