I need to write the correct command that enables me to use the "dblquad" function to solve four integrations with four different variables.
for example: yy = dblquad(….dblquad(@myfun,0,2*pi,0,2*pi))
now the funtion myfun contains phi1,phi2,phi3,phi4 four different variables.
The command line I wrote is not yet complete and I am not sure if it is correct or not.
The myfun should it be then written as follow y = myfun(phi1,phi2,phi3,phi4)
Please I need an answer ASAP
Thank you
