for i=1:6
for j=1:6
f1=@(phi1)(cos(phi1)*i)+2*j;
F=integral(@(phi1)f1,0,1);
end
end
This is the small model of programme which I want to run. This code works if I remove @(phi1) symbol from the integral command, which is possible only for 1-D. But this need to be done for four variable, so I want to make it run in this scenario. Please suggest for solving four variable integral with an additinal 2-D array (i,j-mentioned here) or how to remove @ issue.

@Torsten Really thankful to you. The symbolic Math toolbox is amazing, I tested it for small expression but for 4_D integration and two array functions and it gives result almost immediately.
