inner product of any two vectors x and y in rn. that is, the inputs are x and y and n; the output is (x, y) = x ^t y. in matlab in matlab

To compute the inner product of two vectors x and y in R^n, we can use the dot product function in MATLAB:

main.m
n = length(x); % get the dimension of vectors
inner_product = dot(x, y); % compute the inner product using dot product function

The dot function in MATLAB takes two vectors as inputs and returns their dot product, which is equivalent to the inner product.

Note that both x and y must be column vectors of the same dimension n. If the vectors are row vectors, we can take their transpose to get column vectors:

main.m
n = length(x);
inner_product = x' * y; % compute the inner product using matrix product of transpose of x and y

Here, the ' operator is used to take the transpose of x, and the * operator is used for matrix multiplication.
