I need to solve the following equation. I do not have the knowledge how to write two loops (one loop inside in another loop) for this equation. Please help me to solve this.

here GM and alpha are constant.

sigma_cnm and sigma_snm having number of values.

What have you tried yet?

"I do not have the knowledge how to write two loops (one loop inside in another loop) for this equation."

Search on this forum (and on the internet), you will find many helpful resources.

It seems tthat and are both matrices.

Note that in MATLAB, indexing begins with 1, not 0, so m needs to be defined from 1 to in the second summation.

It may also be necessary to shift n by 1 as well to account for the MATLAB indexing convention.

Hi Prabhath,

Nested loops in MATLAB are loops within loops, where you have an outer loop and one or more inner loops. Each loop can be of any type (e.g., for, while). Nested loops are often used for operations that require iteration over multiple dimensions or levels of computation, such as matrix operations, searching, sorting, or complex summations.

Attaching some starter code here:

% Constants
D = 1; % Example value
G = 1; % Example value
M = 1; % Example value
alpha = 1; % Example value

n = 10 % For Demonstration purposes only

% Define the range
range = 2:15;

% 1st Loop
for i = range
    % 2nd Loop
    for j = 1: n+1
        % Add other logic here
    end
end

I also recommend following the MATLAB Onramp course to get an introduction to MATLAB:

I hope this helps!
