write a function to compute the inner product, element by element (i.e. not using u*v’). in matlab

You can write a function in MATLAB to compute the inner product of two vectors by multiplying the corresponding elements of the vectors and then adding up the products. Here is an example implementation of such a function:

main.m
function result = inner_product(u, v)
    % Check that u and v are the same size
    if ~isequal(size(u), size(v))
        error('u and v must be the same size');
    end
    
    % Multiply corresponding elements and sum the products
    result = sum(u .* v);
end

This function takes two vectors u and v as input, and returns their inner product. The function first checks that u and v have the same size using the built-in function isequal. If they are not the same size, the function will throw an error. Otherwise, the function multiplies corresponding elements of u and v using the element-wise multiplication operator .*, and then sums the resulting products using the built-in function sum. The resulting sum is returned as the output of the function.
