how to evaluate a function with three variables

I am new to Matlab and I am trying to find the RMS of the power. how can i write the code? I guess i have to start with eq(11) to find the power that has a summation

and in that equation I am having three vatiables, time, n2 and Fm. how can I write the loop for that?

>> n1= 30;

>> do= 0.001;

>> %% n2 is the total number of magnetic slabs

>> n2= 78.343;

>> fd= 2170221.96;

>> cv= 0.1875;

>> d33= 6.40e-10;

>> T= 1/n1;

>> % flux density Bd

Bd= (Br/pi)*(atan2d((l*w),(2*d*sqrt(4*d^2+l^2+w^2)))-atan2d((l*w),(2*(tm+d)*(sqrt(4*(tm+d)^2+l^2+w^2)))));

>> t= 0:0.0003:T;

>> pe = (d33^2*n1*N2*pi*fm^2*(sind(n1*N2*pi*t)*(cosd(n1*N2*pi*t))'))/cv;

>> fm= lm*wm*tm^1/3*Br*Bd*fd;

Use “for” loop to solve your equation. Refer the documentation below which contains examples on how to use for loop: https://in.mathworks.com/help/matlab/ref/for.html
