integrating a euler equation

so i have the fallowing euler equation u(du/dx)+v(du/dy) = -dp/dx u,du/dx,v,du/dy are all matrices of 45X50

i already used nested loops to solve for dp/dx to get another 45X50 matrix

i must know integrate dp/dx to get P. how do i go about doing this.

I am also having this problem. would you mind posting your code showing how you used the nested loop to create the 45x50 matrix?
