Question

Write a user-defined MATI.AB function that determines the dot product of two vectors. For the function name and arguments use [D]= last_name_dorpm (u,v). The input arguments to the function are two vectors (any size). The output D is the result (a scalar). Do not use dot building function. Make sure to use for loop (cither while or for). Call this function from your homework file to determine the dot product of.

Answer 1

To write a user-defined function in MATLAB that determines the dot product of two vectors, use a for loop to iterate through the elements of the vectors and perform the dot product calculation. Initialize a variable to store the result and use the formula D = D + u(i) * v(i) inside the loop. Return the value of D as the output of the function.

Step-by-step explanation:

To write a user-defined function in MATLAB that determines the dot product of two vectors, you can follow these steps:

1. Create a function file with the name and arguments specified in the question, for example, function [D] = last_name_dorpm(u,v)
2. Inside the function, use a for loop to iterate through the elements of the vectors and perform the dot product calculation.
3. Initialize a variable, say D, to store the result.
4. Use the formula D = D + u(i) * v(i) inside the for loop, where i is the loop variable.
5. Return the value of D as the output of the function.

Here's an example of how the function would look:

function [D] = last_name_dorpm(u,v)
D = 0;
for i = 1:length(u)
D = D + u(i) * v(i);
end
end

To call this function and determine the dot product of two vectors, you can simply use the function name followed by the two vectors as input arguments.

u = [1 2 3];
v = [4 5 6];
result = last_name_dorpm(u,v);
disp(result);
